title: A genetic electrophoretic variant of high-sulfur hair proteins for forensic hair comparisons. II. Practical application of electrophoretic analysis of hair protein to forensic hair comparisons.
abstract: The influence of weathering and cosmetic treatment on the analysis of human hair-carboxymethylated protein has been studied by a 15% polyacrylamide gel electrophoresis. Usual cosmetic treatment, i.e., permanent waving, dyeing, and bleaching, and weathering, i.e., hair samples that had been buried for up to 2 years, did not evidence any significant change in their electrophoretic patterns, though weathering for 2.5 years or longer made it difficult to determine the electrophoretic patterns. Capillary gel disc electrophoresis of a single, 5 cm, hair strand, which previously had been subjected to ABO blood group determination by an absorption-elution test, was sufficient to provide a multiple protein pattern analysis. Successful use of this analysis in a forensic case is described.
