Abstract
DNA fingerprinting is an important new development for the authentication of cell lines. Multilocus methods such as those developed by Alec Jeffreys provide information on a wide range of genetic loci throughout the human genome and thus give a useful genetic “snap-shot” of a cell culture. Our work has shown that Jeffreys multilocus fingerprinting method can be applied to cell lines from a wide range of animals including reptiles, birds, fish and diverse mammals. It can also differentiate very closely related cell lines including those from the same mouse strain. Routine fingerprint analysis has enabled an unprecedented level of confidence in the consistency of cell stocks. Our results demonstrate that this straightforward method represents a powerful and readily interpreted system for cell authentication and exclusion of cross-contamination.
