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. Webdevelops, the potential for cryptic contamination of short-term studies or stock cultures is consider-able. A culture of 10" organisms/ml is only slightly turbid. Thus a contaminated culture could easily contain more bacteria than mam-malian cells. While the removal rate varied some-what, in no case did the polycarbonate filters re-
