Cryptic contamination

WebAseptic Techniques. To minimize the risk of contamination, follow these 5 rules: 1. Always check the cells carefully before handling (by eye and on a microscope). Become familiar with the indicators of abnormal cell growth. 2. Whenever possible, maintain cultures without antibiotics for at least part of the time, to reveal cryptic contamination. WebMay 28, 2008 · One commonly used method is to predict what the contamination is expected to look like and then test whether the ancient human DNA fulfils this prediction. If it does, the results are rejected as contamination, while if it does not, they are often considered authentic.
