Site Specific Mutagenesis Attempt 4

Dave and Peng are going to beat this thing until it works.

New protocol, based on the Silver protocol on OpenWetWare:

5 µL 10x ThermoPol buffer (Vent) 1.0 µL 10 mM dNTPs 2.5 µL 20 µM forward primer 2.5 µL 20 µM reverse primer 1 µL plasmid DNA 1 µL Vent DNA polymerase 37 uL dH20

PCR Time for 3-9, 6-4, 10-7, cat gene, negative for each

#*95 °C for 2 min. (melt) 
#*95 °C for 0.5 min (melt) 
#*57 °C for 0.5 min. (anneal) 
#*74 °C for 1.5 min. (extension)
#* Go to step 2 (30x)
#*74 °C for 5 min. (final extension; modified from Silver protocol)
#* Keep at 4 °C forever

Total time:  82 minutes +/- some = 90 min

PCR Time for 8-5, cat gene, negative

#*95 °C for 2 min. (melt) 
#*95 °C for 0.5 min (melt) 
#*57 °C for 0.5 min. (anneal) 
#*74 °C for 2.5 min. (extension)
#* Go to step 2 (30x)
#*74 °C for 5 min. (final extension; modified from Silver protocol)
#* Keep at 4 °C forever

Total time: 111 minutes +/- some = 120min
