[Electrofocusing of PGM1 subtypes in blood stains on 100 micrometer polyacrylamide gel over a 4 cm distance]

A technique for PGM1 subtyping of blood stains by isoelectric focusing on 100 microns polyarylamide gel over a distance of 4 cm is demonstrated. There are savings of about 60% regarding material, time, and blood stain volume as compared to the 10-cm distance.
