Screening Recombinant Clones by PCR .
Transfer the transformed clones to a stock LB - Amp or other appropriate plated media .
Grow for 24 hr at 37°C .
Prepare forward and reverse primers for the vector used for transformation at 100 ng / μl in DDH2O .
See table in guidelines for recommended primers to use with pUC18 vector .
Label thin - walled tubes .
Prepare 1 ml of Master Mix :

Vortex and spin Master Mix and dispense 20 μl per thin - walled tube .
Cap all tubes .
Set a 10 μl pipetter to 1 μl .
Place tranformant plate on template and touch the pipette tip to the appropriate colony .
Pipette up and down in the appropriate PCR tube .
Re - cap tube , change tip and repeat steps 9 - 10 until all colonies have been added .
Perform PCR using the thermal cycling protocol :
95°C5 minutes1 cycle95°C55°C70°C30 seconds30 seconds30 seconds * 35 cycles70°C7 minutes1 cycle4 - 10°C Hold cycle * increase to 1 minute if insert is great than 1 Kb .
Remove tubes at end of thermal cycling .
Add 2 μl 10x gel loading buffer to each tube .
Spin to bring contents to bottom of tube and load 10 μl into lane of a 1 % agarose gel in 0.5x TBE buffer .
