Week 10:

08/15/2011
1. Check the transformation of CRISPR+tetR and CRISPR+GFP
2. Inoculate 12 colonies of each, leave them in the shaker
3. Digest CAS3/PCOLA #12 and CASO/PCDF #4, incubate in 37c overnight


08/16/2011
1. Mini-prep all 24 inoculated colonies
2. PCR 12 plasmids of each (GFP+tetR)
Use mixture as follows:
A: GFP spacer Forward+T7 terminator
B: tetR spacer Forward+T7 terminator
C: GFP spacer Reverse+T7 promoter
D: tetR spacer Reverse+T7 promoter
3. Dephosphorylate CAS3/PCOLA
4. Column purify CAS3/PCOLA
5. Run a gel to test CASO/PCOLA
Observation: it didn’t work


08/17/2011
1. Remove overnight PCR and run a gel to check contents of PCR
2. Diluted PCDF+CASO #4 in tetO/R competent cells into 3 different tubes
Notes: each tube had a different combination of contributions to check if PCDF+CASO, tetO/R or both survived
3. Run a gel to test the 24 PCR samples
Observations: from the gel picture, we will pick #2,4,5,6 in GFP::CRISPR, and #1,3,4,5 in tetR::CRISPR, they look clear and reasonable
4. Inoculate the picked samples


08/18/2011
1. Take tube #2, 4, 5, 6
Notes: 6 tubes of LB for each, add 5mL LB, 250 µL of culture, add 5 µL antibiotics, add IPTG 2 hours later after inoculation. Make the
reaction mixture as follows:

ABCDEF
Amp+ + + +

06/11/2011
1. Purify plasmid DNA from the culture
