Alanine Aminotransferase (ALT/GPT) Activity Assay Kit
Cat# E-BC-K235-S-100
Size : 100Assays
Brand : Elabscience
Detection Principle | ALT catalyze the amino conversion reaction between alanine and α-ketoglutaric acid to produce pyruvic acid and glutamic acid at pH 7.4 and 37°C. Then phenylhydrazine was added to form phenylhydrazone with pyruvic acid. Phenylhydrazone is reddish brown under alkaline conditions. ALT activity can be calculated by measuring the OD values at 510 nm. |
Synonyms | ALT;GPT;Glutamic-pyruvic transaminase |
