Colony PCR:
Used to amplify DNA directly from cell culture, the reaction is the same as for normal PCR but with modified reaction composition and cycle settings, here shown for a 50 µl reaction using Taq polymerase.
Reagent | Volume (µl) | Final Concentration |
Water | 35.7 | |
10 mM dNTPs | 1 | 200 µM |
10 x NH4 buffer | 5 | 1x |
Forward Primer | 2.5 | 0.5 µM |
Reverse Primer | 2.5 | 0.5 µM |
Template Cells | 1.3 (from liquid culture or picked colony) | |
Taq polymerase 5u/µl | 1 | 0.1 u/ µl |
Please refer to the standard PCR protocol for the remainder of this protocol.
Notes on colony PCR
- This technique should only really be used for crude PCR assays, such as diagnostic PCR. If high quality DNA is desired, Miniprep followed by standard PCR should be used.
