Summary

The polymorphism of EsD was investigated in tissues of various human organs, dental pulps, hair roots, and seminal stains by isoelectric focusing. The method yielded an excellent resolution of the isoenzyme components. The time limits of determination were: in organ tissues 3 weeks, in dental pulps 1 week, and in hair roots several days. The 7-1 type was less stable than the common types. Phenotyping was possible from fresh semen samples, but was unsuccessful from dried seminal stains after storage. The results show that the EsD typing by isoelectric focusing is of practical use for medicolegal individualization of organs, teeth, and hairs.

Zusammenfassung

Mittels Isoelektrofokussierung wurden die EsD-Typen aus verschiedenen menschlichen Organgeweben, Zahnpulpen, Haarwurzeln und Spermaspuren untersucht. Die Methode erbrachte eine ausgezeichnete Auftrennung der Isoenzymkomponenten. Die zeitlichen Nachweisgrenzen waren: an Organgeweben 3 Wochen, an Zahnpulpen 1 Woche und an Haarwurzeln mehrere Tage. Der Typ 7-1 war weniger stabil als die häufigen Typen. Die Typisierung gelang an frischen Spermaproben, aber an getrockneten Spermaspuren nach Lagerung nicht mehr. Die Ergebnisse zeigen, daß die EsD-Typisierung mittels Isoelektrofokussierung zur rechtsmedizinischen Individualisierung von Organen, Zähnen und Haaren von praktischem Nutzen ist.
