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.

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.
Safety considerations: It is important to observe correct laboratory procedure and wear appropriate clothing and gloves. PCR occurs at high temperature and this may present a risk, depending on the PCR machine employed. For handling the cell culture, appropriate measures should be in place to deal with biohazardous waste.
