ÖZET

The most comman examination in sexual offences is the identifıcation of spermatozoa in aqueous extracts from swabs. Using proteinase K with sodium dodecyl sulphate, it is possible to digest all the cellular material apart from the spermatozoa, resulting in a quik and effective method of their isolation. Spermatozoa were detected in 8 extracts using this treatment when the normal method had failed to reveal all but one of them.
