Screening for Insertion of Lox/Gen Cassette in pKn004 (pKn006)
Rxn Mix
Reagent | Volume/Amount |
Paeru Genomic DNA Template | 0.5 μl from So Pa Pan stock |
Taq | 0.5 μl |
M13 for | 4 μl 1 μM Stock |
BT1188 | 4 μl 1 μM Stock |
dNTPs | 1 μl 10 mM Stock |
DMSO | 2.5 μl |
Buffer | 5 μl |
Mg2+ | 2.5 μl |
dH20 | 30 μl |
Total | 50 μl |
Rxn Conditions
Annealing Temperature: 55oC (2.3 degrees below annealing temp of BT1188)
Extension Time: 2 minute 40 seconds (~2.6 kb at 1 kb/min ~2.5 min)
- Note: If the cassette hasn't been ligated into pKn004, this PCR will yield a product of length ~1500 bp.

Run Notes
7.31.08
Ran a colony PCR on the sole pKn006.L1 transformant. 10 μl reaction: Used 1 μl colony suspension, 1 μl Taq (too much, but small volume hard to pipette), 0.8 μl M13_for (note I had to make a fresh batch this time, 1 μl supposedly 100 μM stock in 99 μl water), 0.8 μl M13_rev, 0.5 μl dNTPs (again, too much but small volume), 0.5 μl DMSO, 1 μl buffer, 0.5 μl Mg2+, 6 μl water. Used reaction conditions as written in protocol. Gel results here.
8.5.08
Ran colony PCRs on 7 putative pKn006.L2 transformants. Made a master mix and aliquotted to each of 9 tubes, then added 1 μl colony suspension (colony in 25 μl water) to each reaction. Ran PCR according to protocol. Gel results here.
