Purification of YopH - 12/3/2013
The YopH enyme that was expressed was purified using the affinity tag and the Ni-NTA resin.

Expression of YopH - 11/21/2013
The YopH enzyme was transformed into BL21(DE3) cells in order to be expressed.

From TbPP2A to YopH - 11/21/2013
After several attempts of cloning, a positive clone of //Trypanosoma brucei// PP2A was not obtained. As a result, we have to move towards the surrogate enzyme YopH. Expression, purification, and characterization will be done on this enzyme. In addition, different concentration of the YopH enzyme will be tested in enzyme assays.

=**__Week 11 & 12__**=

Ligand Preparation - 11/14/2013
====The protocol of Ligand preparation was completed in order to make the ligands ready to be screened. The CB-kit_UT.sdf library is currently being screened through GOLD on the homology model of T. brucei PP2A.====

Blast Nucleotide Comparisons for Miniprep samples (fourth time) - 11/12/2013
After receiving the DNA sequences of the 18 samples sent to DNA sequencing, a blast nucleotide comparison was done. The two sequences compared were the one of T. Brucei PP2A with each of the the cloning attempts of Tb PP2A (eight samples). All of these blast comparisons showed no similarity. Most of these sequences contained a lot of N's and they were really short. In addition, an email from dfscore was received saying that there might be something wrong with the primers that were used. As a result, few of these samples will be sent again to DNA sequencing using other pLIC-forward and reverse primers in order to know if these are positive clones or not.

DNA Sequencing - 11/8/2013
All the samples obtained from mini-prep, except number 9, were sent to DNA sequencing with pLIC-forward and pLIC-reverse



Mini Prep - 11/8/2013
Mini prep was done on the nine pellets obtained from the nine transformation tubes from the second master plate (the one with 3 ul accepting vecot & 5 ul of insert). Instructions for this step were done following the manual in the miniprep kit. All of the samples were eluted with 50 ul of water and the concentrations for these samples are shown below.



















Spin down samples - 11/7/2013
Samples were spun down at 6000 rpm for 10 minutes at 4 C. Supernatant was removed. Samples from the 9 tubes of the master plate containing colonies of 3 ul of accepting vector and 5 ul of insert will be used to do mini-prep. On the other hand, the pellets obtained from the transformation tubes of the plate with 2 ul of accepting vector and 4 ul of insert were stored at -20 C.

Master plate - 11/5/2013
Two master plates were prepared with 9 colonies from each of the transformation plates done on 11/4/2013. The transformation tubes were also prepared. However, there was an error made on this step. Instead of adding 5 ml of LB and 5 ul of Kanamycin to each tube, 5 ml of LB and 5 ul of Ampicillin were added to each tube. As a result, no bacteria grew on the tubes, but it still grew on the master plates since it contained Kanamycin. The transformation tubes were prepared again using the colonies from the master plates.





Plates were moved from 37C incubator to 4C fridge - 11/5/2013
The two plates of the annealing and the transformation step were on the 37 C incubator for a day. Then, they were moved to the 4 C fridge.

Annealing and transformation - 11/4/2013
The procedure for annealing and transformation was immediately done after finishing the cohesive ends of both the accepting vector and PCR insert. In this procedure, two transformation tubes were used. Tube A contained 2ul of T4-treated accepting vector with 4ul of each T4-treated insert. Tube B contained 3 of T4-treated accepting vector with 5 ul of each T4-treated insert. 25 ul of competent cells (DH5a) were added to both tubes. Then, they were incubated on ice for 30 minutes. After this they were heat shocked for about 30 seconds in 42 C water bath. Then, 100 ul of pre-warmed SOC was added to each tube. Next, the tubes were shaked for 1 hour in 37 C shaker. After this, the transformation mixture was spread onto LB-Agar plates with 50 ug/ml Kanamacyn and 5% sucrose. Finally the plates were incubated upside down at 37 C for one day.





=**__Week 9 & 10__**=

Preparation of the ligands - 10/29/2013
Since it is best to protonate the ligands and generate alternative ionization and tautomeric states, the control ligands were prepared. These ligand preparation methods applied a Force Field to each atom and subsequently carried out an Energy Minimization process to put the ligand in a low energy conformation that is more probable as a starting point in solution. These ligands will then be used for docking our protein.

Positive and negative controls for PP2A - 10/28/2013
11 positive controls were found through the literature of 2NPP, the PDB structure that was used to make our homology model, and through other PDB structures that are very similar to our target, Tb.PP2A. The negative controls were found using Chembridge website and similar properties as the known inhibitors of PP2A like microcystin.

Transformation plates after being incubated at 37 C - 10/24/2013




As it is observed, the plates did not grow as clean of colonies as expected. In an effort to fix this situation, I decided to swipe some of the bacteria from each plate and spread it out on new plates (respectively), in order to regrow the bacteria in better looking colonies. However, one colony from the 2ul T4 treated accepting vector and the 8ul T4 treated insert was picked and chosen to make a master plate.

Annealing and transformation - 10/22/2013
The procedure for annealing and transformation was immediately done after finishing the cohesive ends of both the accepting vector and PCR insert. In this procedure, two transformation tubes were used. Tube A contained 2ul of T4-treated accepting vector with 8ul of each T4-treated insert. Tube B contained 3 of T4-treated accepting vector with 6 ul of each T4-treated insert. 25 ul of competent cells (DH5a) were added to both tubes. Then, they were incubated on ice for 30 minutes. After this they were heat shocked for about 30 seconds in 42 C water bath. Then, 100 ul of pre-warmed SOC was added to each tube. Next, the tubes were shaked for 1 hour in 37 C shaker. After this, the transformation mixture was spread onto LB-Agar plates with 50 ug/ml Kanamacyn and 5% sucrose. Finally the plates were incubated upside down at 37 C for two days since they did not show colonies the first day.

**__Week 7 & 8__**

**Nice work Jacky. Very well organized and analyzed. Do you have any virtual data? -Max 10/21/13
pNIc-Bsa4 preparation as an accepting vector - 10/16/2013 More pNIC-bsa4 was prepared as an accepting vector in order to do another round of cloning to find a positive clone of PP2A.

PCR clean up - 10/11/2013
PCR clean up was done in Secondary PCR sample 3 obtained on 8/30/2013. Another PCR clean up was done in all of the Secondary PCR samples from 8/30/2013. The Sigma PCR cleanup kit in red box was used for this procedure.



===Note: The concentration obtained from PCR clean up was really good. In addition, the 260/280 and 260/230 values are in the range expected, which shows that the purity of the sample is good. This PCR clean up sample will be used for cloning.===

PCR Squared Reaction - 10/11/2013
Eight samples of PCR squared reaction were done using the secondary PCR. An agarose gel was run with these samples to verify that they worked correctly.

Cloning did not work - 10/11/2013
After the plates were incubated upside down at 32 C for one day, there were no colonies in both plates. Therefore, the plates were incubated another day. However, there were still no colonies, and this shows that cloning did not work. As a result, more PCR squared reaction will be done using the same thermocycler conditions as before and then PCR clean up on these samples in order to go into cloning again.



Annealing and Transformation - 10/10/2013
The procedure for annealing and transformation was immediately done after finishing the cohesive ends of both the accepting vector and PCR insert. In this procedure, two transformation tubes were used. Tube A contained 2ul of T4-treated accepting vector with 8ul of each T4-treated insert. Tube B contained 3 of T4-treated accepting vector with 10 ul of each T4-treated insert. More T4-treated insert was added to each tube since we had a low concentration of the PCR sample. 25 ul of competent cells (DH5a) were added to both tubes. Then, they were incubated on ice for 30 minutes. After this they were heat shocked for about 30 seconds in 42 C water bath. Then, 100 ul of pre-warmed SOC was added to each tube. Next, the tubes were shaked for 1 hour in 37 C shaker. After this, the transformation mixture was spread onto LB-Agar plates with 50 ug/ml Kanamacyn and 5% sucrose. Finally the plates were incubated upside down at 37 C for one day.

Gel extraction on PCR squared reaction - 10/9/2013
A gel was run using all the samples from PCR squared reaction made on 10/4/2013. New TAE was used in order to prevent contamination. For this procedure, the gel was cut were the bands of the gene were shown and then the gel extraction kit was used to follow the procedure of the gel extraction protocol. There were several errors while adding the solutions to the gel and the procedure took longer than what it should take. After finishing this protocol, the concentration of the PCR sample was measured using a nanodrop spectrophotometer. The concentration was not as high as expected and this could be due to the errors made. A picture of the gel before it was cut and the nanodrop images are shown below.

Positive and negative controls for virtual screening - 10/8/2013
Two positive and one negative control were found. They were run using the GOLD pogram in order to see which one has a higher score. The controls obtained are shown in the table below. However, we still need to find more controls in order to do another run with our protein.



**__Week 5 & 6__**
=**Nice Job with keeping your work up to date. Please try to add a more detailed description for your homology model. Thank you. -Max 10/07/2013=

PCR Squared Reaction - 10/4/2013
Eight samples of PCR squared reaction were done using the new secondary PCR. This time, we will not use 15ul of these samples in an agarose gel to check if these reactions worked correctly. Instead, we will put all of the samples in the agarose gel and we will do gel extraction. This procedure will be done on Monday 10/7/2013. Then, we will continue with PCR clean up and with cloning to find a postive clone.

Blast Nucleotide Comparisons for Miniprep samples (second time) - 10/4/2013
The eight samples obtained from the second miniprep that was done were sent to DNA sequencing. After receiving the DNA sequences, a blast nucleotide comparison was done. The two sequences compared were the one of T. Brucei PP2A with each of the the cloning attempts of Tb PP2A (eight samples). All of these blast comparisons showed no simmilarity; therefore, they cannot be used for the next step. Another round of cloning will be done and hopefully a positive clone can be found.

Homology Model - 10/3/2013
A homology model was created since protein phosphatase 2A does not have one.





Mini Prep - 9/27/2013
Mini prep was done on the eight pellets obtained from the eight transformation tubes from the second master plate. Instructions for this step were done following the manual in the miniprep kit. This time the samples were eluted with the right amount of water, 50 ul.

















Note: Most of these samples have really good concentrations and higher than expected; however, the 260/280 and 260/230 values are lower than the average. These values show that the samples are not pure and do not have a good yield.

Secondary PCR - 9/26/2013
Two samples of secondary PCR were done using the same thermocycler cycling conditions that were used the last time it worked.

Blast Nucleotide Comparisons for Mini prep samples - 9/25/2013
The DNA sequence obtained from sample 2 of mini prep did not show a complete sequence. The Blast nucleotide comparison gave a 30% of query and 99% of identity. As a result, this sample cannot be used for the next step.

The Blast nucleotide comparison for the DNA sequence of T. Brucei PP2A and the cloning attempt of Tb PP2A (sample 3) gave a 99% of query and a 98% of identity. These percentages are really good. However, since it has a deletion in base pair # 208, it cannot be used for the following step.



The Blast nucleotide comparison for the DNA sequence of T. Brucei PP2A and the cloning attempt of Tb PP2A (sample 5) gave a 89% of query and a 99% of identity. These percentages are really good. However, since it has two deletions, it cannot be used for the following step.



The Blast nucleotide comparison for the DNA sequence of T. Brucei PP2A and the cloning attempt of Tb PP2A (sample 7) gave a 93% of query and a 96% of identity. These percentages are really good. However, since it has two deletions, it cannot be used for the following step.

===Note: Mini prep will be done again. This time we will use the tubes obtained from the other master plate that was done. In addition, more secondary PCR will be done in order to be prepared for another round of cloning in case this one does not give a positive clone.===

=**__Week 3 & 4__**= Jacky - good work on cloning for this 2 week block. Keep moving it foward though so that we can get your positive clones and move on to the next step. - Dr. B 100113

DNA Sequencing - 9/20/2013
Samples of the miniprep done in tube 2, 3, 5, and 7 were sent to DNA sequencing.



Mini Prep - 9/20/2013
Mini prep was done on the eight pellets obtained from the eight transformation tubes. Instructions for this step were done following the manual in the miniprep kit. However, in the elution step there was an error made. Instead of eluting with 50ul of water or 5mM Tris HCL pH 8.0, all of the samples were eluted with 100 ul of water. This error affected the concentrations of the samples.

















Spin down samples - 9/18/2013
Samples were spun down at 6000 rpm for 10 minutes at 4 C. Supernatant was removed and transformation tubes were stored at -20 C.

Master plate - 9/17/2013
8 colonies from the transformation plate containing the transformation mixture of tube B were grown for about 18 hours in 5 ml of LB with 50 ug/ml Kanamacyn. In addition, a master plate using those colonies was done and incubated at 37 C overnight.

Plates were moved from 37C incubator to 4C fridge - 9/15/2013
The two plates of the annealing and the transformation step were on the 37 C incubator for a day and a half. Then, they were moved to the 4 C fridge.

Annealing and Transformation - 9/13/2013
The procedure for annealing and transformation was immediately done after finishing the cohesive ends of both the accepting vector and PCR insert. In this procedure, two transformation tubes were used. Tube A contained 2ul of T4-treated accepting vector with 4ul of each T4-treated insert. Tube B contained 3 of T4-treated accepting vector with 6ul of each T4-treated insert. 25 ul of competent cells (DH5a) were added to both tubes. Then, they were incubated on ice for 30 minutes. After this they were heat shocked for about 30 seconds in 42 C water bath. Then, 100 ul of pre-warmed SOC was added to each tube. Next, the tubes were shaked for 1 hour in 37 C shaker. After this, the transformation mixture was spread onto LB-Agar plates with 50 ug/ml Kanamacyn and 5% sucrose. Finally the tubes were incubated upside down at 37 C for about a day and a half.

Preparation of pNIC-Bsa4 as Accepting Vector - 9/13/2013
The preparation of pNIC-Bsa4 as an accepting vector was done by Kevin.






 * NOTE: After taking a picture without the rig, the strange imaging at the bottom of the gel disappeared.**

PCR clean up - 9/13/2013
PCR clean up was done in Secondary PCR sample 3 obtained on 8/30/2013. Another PCR clean up was done in all of the Secondary PCR samples from 8/30/2013. The Sigma PCR cleanup kit in red box was used for this procedure.









As it is observed in the graphs shown above, the concentration of the PCR clean up done on the PCR2 squared reaction was really low. Therefore, it cannot be used for the next step. However, the concentration of the PCR clean up of all the secondary PCRs samples was really high, which is really good. This sample will be used for the following step.

PCR squared reaction - 9/12/2013
PCR squared was done on Secondary PCR sample 3 obtained on 8/30/2013. The purpose of this step was to make a lot of PCR product since a lot of it will be lost in the PCR cleanup steps. The thermocycler cycling conditions used for this protocol were the same as in Secondary PCR. The only difference was the amount of cycles, which in this case was 30.

PyMOL Refresher - 9/4/2013
In order to refresh basic technical and analytical skills of the PyMOL Program, four versions of DHFR were analyzed. Human DHFR was compared to T.cruzi DHFR. This comparison showed that the MTX active sites of both proteins are very similar. On the other hand, when the Human DHFR active site was compared to the T.cruzi TMQ active site, it was found that the two active sites are different. Therefore, the TMQ active site can be targeted specifically, while causing no inhibition of Human DHFR. = = = = = =

 * Lane 2:** 1 kb DNA ladder
 * Lane 3:** Uncut plasmid sample
 * Lane 4:** EcoRI
 * Lane 5:** PvuII
 * Lane 6:** EcoRI & PvuII
 * Lane 7-10:** Kevin's samples


 * Note: Samples were done on 6/28/13, but the gel was done on 7/2/13. Digestion reactions were stored in -20C freezer. Samples did not show up; therefore, protocol has to be redone. The problem seems to be in the pGBR22 plasmid that was used since it did not work for anyone.**

Protein Characterization - 6/28/2013
Gel is being washed over the weekend. On Monday, a picture of the gel will be taken and the gel will be dried.

Protein Purification - 6/26/2013

 * Lane 10:** sample 8, no DNA, 1 ul Taq


 * Note: The samples with the primers VDS 1 and 2 did not show any results. The only sources of error are in the temperature used or the PCR machine used since the Taq, buffer, and dNTP were the same ones used for the M13 forward and reverse primers, which showed up on the gel.**

Analysis of DNA sequencing of pGBR22 - 6/24/2013
DNA sequence of pGBR22 was analyzed in the computer lab. T he forward and reverse primers were determined, as well as the location of the start and stop codon of the specified plasmid and the vector backbone.

PCR for GFP (Trial 2) - 6/20/2013
This protocol was done for the second time since the first one did not show anything. The primers VDS1 and VDS2 were used for samples 1 through 4 and primers M13 forward and reverse were used for samples 5 through 8. Two PCR machines were used due to the different temperatures needed for the primers in the third step. For VDS2 the temperature used was 53.6 C instead of 55.6 C and for M13 the temperature was 42 C again. One of the PCR machines was used for the first four samples and the other one for the other four samples.

PCR for pGBR22 (Trial 3) - 6/20/2013
This protocol was done for the third time since the results of the first two trials did not work correctly. This time, the primers used were M13 forward and reverse instead of SP6/T7. Also, a different PCR machine was used.

Protein Expression - 6/17/2013 to 6/19/2013

 * Day 1:** Transformation of FtHAP plasmid into BL21(DE3) cells.
 * Day 2:** Overnight cultures.
 * Day 3:** Purification of the FtHAP protein.
