July 9
- Jasmine & Joe
- Checked 10 CP-EP* colonies with colony PCR
- Cultured colonies 5 and 7 in TB-Amp
- Michelle
- Culture SBP-LRP plasmid
- Jeremiah & Chris:
- TBP+++ purified and digested (gel 066)
- Digestion of SBP-TBP to use with new expression vector
- XbaI and PstI
- Justin & Dafne
- Ligate SBP into SBP-B12 plasmid
- Transform into TOP 10 competent cells
July 10
- Jasmine and Joe:
- Miniprepped CP-EP* cultures
- Digested CP-EP* with SpeI and NsiI
- Dephosphorylated CP-EP* digestion
- Ligated RFP* with CP-EP*
- Created new primer stocks for VR, VF2, and a new EP*-anti-SpeI
- Amplified new EP (EP^), lac promoter, and tet promoter using PCR
- Michelle:
- Grew SBP-LRP plasmid from transformation of SBP (SpeI and PstI) and LRP (PstI and XbaI)
- Miniprep of SBP-LRP plasmid from transformation of SBP (SpeI and PstI) and LRP (PstI and XbaI), nanodrop, and :::pellet since 1st miniprep concentration was too little. Pellet was then miniprepped and nanodropped.
- Digest transformation SBP (SpeI and PstI) + LRP (PstI and XbaI) with XBA I and PST I,
- run through gel, and ligate with EP.
- Jeremiah & Chris:
- Ligation of SBP-TBP à ExV using new method
- Justin and Dafne
- SBP-B12-SBP transformation successful
- Multiple colonies grew, and colony PCR check confirms
- SBP-B12 in expression plasmid turned out to be unsuccessful
- Digest SBP-B12 plasmid by Xba I and Pst I HF
- Ligate into new expression plasmid
July 11
- Jasmine and Joe:
- Transformed ligated RFP*-CP-EP* into competent cells and plated onto 1 amp plate with L-arabinose and one without
- Transformed original CP plasmid into competent cells and plated onto 1 amp plate with L-arabinose and one without
- Digested lac promoter and tet promoter with EcoRI and SpeI
- Michelle:
- Transformation of ligation SBP (SpeI and PstI)-LRP (PstI and XbaI) plasmid digested with
- XBA I and PST I and EP onto AMP plates.
- Jeremiah & Chris:
- Transformed SBP-TBP-ExV
- Colonies were too numerous to count (TNTC)
- Justin and Dafne
- Transform ligation of SBP-B12 insert into expression
- TOP10 competent cells were used
July 12
- Michelle:
- Check transformation of SBP (Spe1 and PstI)-LRP (PstI and XbaI) digested with XbaI and PstI + EP on AMP plates.
- PCR colony check 24 colonies with Forward primer (Control promoter) and Reverse primer (Terminator) and ran gel.
- Jeremiah & Chris:
- Colony PCR of plate #1
- No positive colonies or failed PCR
- Justin and Dafne
- Colony PCR check of colonies produced by SBP-B12 in expression plasmid transformation
- Colony check successful
- Culture successful colony in LB-amp overnight
July 13
- Michelle:
- PCR check colony #9 from transformation of SBP (SpeI and PstI)-LRP (PstI and
- XbaI) digested with XbaI and PstI + EP with Forward primer (Control promoter) and Reverse
- primer (Lysine antisense) and ran gel to double check if PCR colony #9 is truly successful.
- Cultured 2 new colonies from 7/10 KAN plates containing successful transformation of SBP (SpeI and PstI) and LRP :::PstI and XbaI) with TB-KAN broth.
- Jeremiah & Chris:
- Colony PCR of both plates again
- Culturing colony 1-9 from plate #1 and colony 2-4 from plate #2
- Ligation of SBP-TBP into constitutive vector – transformed on 07/15
- Justin and Dafne
- once OD of the over night culture reached 0.6, L-arabinose was added in varying concetrations
- Tube 1: 0.001% Tube 2: 0.01% Tube 3: 0.1% Tube 4: 1.0%
- Control: SBP-B12 expression plasmid not induced by L-arabinose
- After 4 hours, time sample 1 was pelleted and placed in -80 freezer
- After 8 hours, time sample 2 was pelleted and placed in -80 freezer
- once OD of the over night culture reached 0.6, L-arabinose was added in varying concetrations
