γ-glutamyl transpeptidase (γ-GT)

L-Type γ-GT.JFor In Vitro Diagnostic Use

Intended Use

L-Type γ-GT.J is an in vitro assay for the quantitative determination of the activity of γ-glutamyl transpeptidase (γ-GT) in serum or plasma.


JSCC Transferable Method

Special Characteristics

L-Type γ-GT.J is a liquid reagent which is highly precise and stable to be designed for general biochemical automated analyzers.

Principle of the Method

When a sample is exposed to the Buffer and Substrate, the γ-glutamyl group of the substrate L-γ-glutamyl-3-carboxy-4-nitroanilide is transferred to glycylglycine by the action of the γ-GT, contained in the sample, resulting in the formation of L-γ-glutamyl-glycylglycine and liberation of 5-amino-2-nitrobenzoic acid. The γ-GT activity in the sample is then determined by measuring the rate of 5-amino-2-nitrobenzoic acid production.
