title: A new fluorescence method for gamma-glutamyltransferase isoenzyme demonstration.
abstract: A new fluorescence method for demonstrating gamma-glutamyltransferase isoenzymes using gamma-glutamyl-5-amino-4-methyl coumarin, a commercially available, non-carcinogenic substrate is described. The procedure can readily detect gamma-glutamyltransferase isoenzymes in samples with total activity as low as 5 U/l at 30 degrees C.
