title: Determination of phenotypes of phosphoglucomutase (PGM1) in bloodstains by cellulose acetate electrophoresis.
abstract: A good separation of PGM1 isoenzymes from bloodstains has been obtained with an adapted Sonneborn method of electrophoresis on cellulose acetate. This method requires very small quantities of the examined material, a short time of electrophoresis, and is cheaper and simpler than hitherto described. A correct determination of PGM1 phenotypes from bloodstains was easy up to 24 weeks. Occasionally it was possible to determine phenotypes in bloodstains as old as 47 weeks, and in one case even in bloodstains 126 weeks old. This method may be useful in the forensic serology for determination of PGM1 phenotypes from bloodstains.
