Analysis Note

Protein determined by biuret

Application

Glutamic-Pyruvic Transaminase from porcine heart has been used:in the transamination assay with a racemic mixture of synthetic 3-methyl-2-oxoglutarateto remove glutamate from the cell culture medium used for culturing human embryonic kidney (HEK293) cells in the lactate-dehydrogenase (LD)-coupled alanine transaminase (ALT) reaction kinetic studies

Biochem/physiol Actions

Glutamic-pyruvic transaminase (GPT) is located in most cells in the body, but is found in highest concentrations in the liver. It is used as a marker of liver disease due to the release of GPT into the blood following liver cell necrosis.

Glutamic-pyruvic transaminase (GPT) mediates the transfer of the amino group to α-ketoglutarate from l-alanine. It plays a key role in gluconeogenesis and amino acid metabolism. The role of GPT in various kinds of tumors has been reported.

General description

Glutamic-pyruvic transaminase (GPT) is localized majorly in the liver.
