STR typing of human telogen hairs - a new approach

A new approach to short tandem repeat (STR) typing of DNA extracted from te logen shed hairs is presented. Newly designed primer pairs with annealing p ositions close to the repeat units of the STR loci HUMFES, HUMTH01 and HUMT POX were used for amplification. The typing results were compared to those obtained by the commonly used primer pairs by means of success rates. The p rimer pairs capable of producing very short amplicons (< 106 bp with HUMFES , < 86 bp with HUMTH01 and < 87 bp with HUMTPOX) described in this study si gnificantly increased the success rates when typing telogen hairs.
