Phosphoglucomutase1 (PGM) subtyping and esterase D phenotyping were simultaneously performed by electrophoresis of bloodstained fibers using agarose and a Tris-maleic acid buffer system, pH 5.4. This method reduces anodal gel shrinkage and shortens development time when compared to the conventional electrophoretic technique for PGM subtyping which is performed at pH 7.4 using an agarose-starch substrate.
