PGM1, ESD, and ACP were determined in bloodstain extracts by isoelectric focusing (IEF) with carrier ampholytes (CA) and HIEF. HIEF yields superior results in PGM typing from bloodstain extracts, whereas for ESD and ACP typing isoelectric focusing with carrier ampholytes seems to be the method of ch

✦ Synopsis
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 yon PGM~ aus Blutspuren durch Adaptierung der Sonneborn-Methode mit der Celluloseacetat-Elektrophorese erreicht. Nur sehr kleine Mengen yon 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 Ph~inotypen PGM~ aus den Blutspuren bis zu 24 Wochen st6gt auf keine Schwierigkeiten. Gelegentlich war die Ph/inotypenbestimmung auch in ~ilteren Blutspuren m6glich: bis 47 Wochen, und in 1 Fall sogar bis 126 Wochen. Die Methode kann in der forensischen Serologic bei der Blutspurenuntersuchung brauchbar sein.

The existence of four alleles of phosphoglucomutase (PGM1) in human red cell lysates has previously been demonstrated by isoelectric focusing (Bark et al., 1976; Kühnl et al., 1977; Sutton and Burgess, 1978). Experiments are now described in which the position of each of the first-locus (PGM1) and s
Phosphoglucomutase (PGM1) phenotypes were determined in a population sample of Tuscany, Italy, by isoelectric focusing. The frequencies observed for the four alleles are: PGM1+1 = 0.6012, PGM1-1 = 0.1059, PGM2+1 = 0.2495, PGM2-1 = 0.0434. Two variants were detected and it was possible to study the p
The technique of isoelectric focusing on methylated 'cellogel' strips (CAGIF) was used to confirm the presence of four alleles of PGM1 in human red cell lysates. The subtypes of PGM1 were determined in two Polish population samples, from Southwestern Poland (Wrocław region, n=321) and Southeastern P
