The use of gamma-glutamyl-p-aminobenzoic acid as the substrate for determination of gamma-glutamyltranspeptidase activity in blood serum.
By the phthaloyl method less toxic and readily soluble gamma-L-glutamyl-p-aminobenzoic acid was synthesized. This substance was used as a substrate for gamma-glutamyltranspeptidase activity assay in blood serum and urine. Close correlation was shown between the results obtained with the new method and with the old one which used gamma-L-glutamyl-p-nitroanilide.
