Summary

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.

Zusammenfassung

Es wird eine gute Trennung der Isoenzymmuster von PGM1 aus Blutspuren durch Adaptierung der Sonneborn-Methode mit der Celluloseacetat-Elektrophorese erreicht. Nur sehr kleine Mengen von untersuchtem Material und kurze Zeit der Elektrophorese sind bei dieser Methode erforderlich, die Technik ist billiger und einfacher als die bisher angewendete. Eindeutige Bestimmung der Phänotypen PGM1 aus den Blutspuren bis zu 24 Wochen stößt auf keine Schwierigkeiten. Gelegentlich war die Phänotypenbestimmung auch in älteren Blutspuren möglich: bis 47 Wochen, und in 1 Fall sogar bis 126 Wochen. Die Methode kann in der forensischen Serologie bei der Blutspurenuntersuchung brauchbar sein.
