Multiple Enzyme Typing of the Sheath Cells Associated with the Root of a Single Human Head Hair

Abstract

Multiple-enzyme typing of the cellular material associated with single human head hairs can be achieved quite readily using cut sections of hair, and 60/100 petroleum ether to dissolve the XAM mountant. Both the PGM 1 (IEF) and GLO I systems could be determined from hair sections after 2 months and PGM 1 typing of the sheath cells associated with complete hairs, from some donors, has been achieved after 4 months storage in XAM. EsD activity was lost after storage in XAM and typing was rarely possible even with air storage for periods in excess of 4 weeks.
