[Glyn Stacey] 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 Òsnap-shotÓ 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... , "[W. B„r] DNA fingerprinting is a perfect tool for investigating the identity of disputed blood by alcoholsamples extracted. However, blood samples stored at an ambient temperature for longer periods canshow considerable degradation of high-molecular DNA, diminishing the value of fingerprintinvestigation because of loss of the less frequent bands formed by the longer DNA fragments.Addition of the complexing agent EDTA can retard this degradation. Determination of the sex with DNAprobes in the blood alcohol sample increases confidence in the investigation...
