title: Sex determination and species exclusion in forensic samples with probe cY97.
abstract: A total of 120 human samples of blood, saliva and semen stains, hair roots, bone and skin fragments, obtained from 30 males and 16 females were analyzed in Southern blots with probe cY97. Only the male samples gave a specific band of 5.7 kb. In dot blot, under high stringency conditions, male DNA gave signals equivalent to a quantity of female DNA eight times higher. Probe cY97 did not react with 9 different vertebrate species but gave a signal for monkey DNA when used at low stringency. The advantage of using a probe specific for the centromeric region for sex determination and species exclusion is discussed.
