Isoelectric focusing of human hair keratins: correlation with sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) patterns and effect of cosmetic treatments.

Abstract excerpt

A new isoelectric focusing (IEF) technique in polyacrylamide gels with 6M urea and 1.5% Nonidet P40 has been developed to characterize human hair samples. The phenotypes demonstrated with this procedure has been correlated with the sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) patterns described by other authors. The method described can be applied in the forensic science analysis of a...
