چکیده

We describe the preparation of a new substrate, N-gamma-L-glutamyl-5-aminoisophthalic acid dimethyl ester hydro-chloride, for the fluorometric determination of gamma-glutamyltransferase activity in serum by the "front-surface" technique. Details of the resulting method are provided. The final reaction mixture contains 4 mmol of the substrate per liter of tris(hydroxymethyl)aminomethane (100 mmol/liter) and glycylglycine (75 mmol/liter) at pH 8.2 (25 degrees C).

Relationships of Serum Level of High- Sensitivity C- Reactive Protein (hs- CRP) and White Blood Cell (WBC) Count with Gamma- Glutamyltransferase among Iranian Healthy Adults

Background & Objective: There are many common infections and inflammations among people over the world. This demands an affordable and reliable test with high sensitivity/specificity to predict or confirm the diagnosis of such cases in routinely clinical practice. In the present study, we aimed to find any potential correlation between serum levels of GGT and CRP- Q and/or hs- CRP and ...

Gamma-glutamyltransferase: Substrate inhibition, kinetic mechanism, and assay conditions.

Gamma-glutamyltransferase activity in serum is shown to be competitively inhibited by the two substrates gamma-glutamyl-4-nitroanilide and glycylglycine. Awareness of this is of importance when one is choosing final reaction conditions for the assay of the enzyme. Gamma-glutamyltransferase probably acts by a "ping-pong bi-bi" kinetic mechanism, which fits with the double competitive substrate i...

Hepatic gamma-glutamyltransferase activity in alcoholic fatty liver: comparison with other liver enzymes in man and rats.

Compared with controls, patients with alcoholic fatty liver showed a significant increase of gamma-glutamyltransferase activity both in the liver and serum, whereas alkaline phosphatase activity was raised only in the liver but not in the serum. The activities of other enzymes such as aspartate aminotransferase, alanine aminotransferase and glutamate dehydrogenase remained virtually unchanged i...

Gamma-glutamyltransferase, atherosclerosis, and cardiovascular disease: triggering oxidative stress within the plaque.

The serum determination of gamma-glutamyltransferase ( -GT) activity is a low-cost, highly sensitive and accurate, and frequently used laboratory test. Although it is considered to be an index of hepatobiliary dysfunction and alcohol abuse,1 recent epidemiology and pathology studies have suggested its independent role in the pathogenesis and clinical evolution of cardiovascular diseases brought...

A fluorometric determination of trypsin-like amidase activity and activity of trypsin inhibitors in serum.

The activity of crystalline trypsin and the trypsin-like amidase activity and the activity of trypsin inhibitors in serum were measured fluorometically, with a-benzoyl--L-arginine--na phthylamide (BANA) as substrate. The method is simpler and more sensitive than the colorimetric method based on the Bratton-Marshall reaction. Serum of pancreatectomized dogs hydrolyzed BANA at a significant rate,...
