g-glutamyltransferase Assay Kit is an Assay Kit by IFCC Method.Based on the bottle type, product model can be classified in to Hitachi 7170, Hitachi 7060, Hitachi 7020, Beckman, Toshiba, Mindray, DuPont, Innova, Siemens, KHB, Abbott, Universal types, etc.This reagent is used to determine the g-GT activity in human serum.Under the catalytic action of g-GT in the sample , in presence of glycylglycine , the substr ate L - g-glutamyl - 3 - carboxy - 4 - nitroanilid e is converted to yellow colored 5 - amino - 2 - nitrobenzo ate and increase absorbance at 405nm. The increase rate of absorbance is proportional to the activity of g- GT in the sample. table, th, td { border: 1px solid black; border-collapse: collapse; } th, td { padding: 10px; } R1: Reagent CompositionR2: Reagent Composition
