E.coli colony PCR

1. Pick a fresh colony of about 1 mm and resuspend it in 10 µl water.
2. Use 1 µl as a template for a 25 µl PCR reaction.

Yeast colony PCR

1. Aliquot 20 µl NaOH (20 mM) into 1.5 ml tubes
2. Pick colonies (use pipet tips) into the NaOH
3. Incubate at 95°C for ~ 45 minutes
4. Centrifuge at max speed for 10 minutes
5. Use 5 µl of supernatant as template in a (50 µl) PCR.
