[RFLP analysis of single hairs].

Abstract

Investigations were performed with the root of one hair torn out 6 times in parallel. Yield of DNA was about the same with 6 extraction methods tested. Hairs stored at RT up to 8 weeks in non sterile environment showed the same result as deeply frozen hairs. Hairs of one test person could not be typed in repeated investigations, whereas hairs of another person could successfully be typed in every case (n > 100). 35 hairs of 66 samples investigated from 11 other persons could be typed.
