The human AST ELISA Kit is intended to measure human AST in serum, plasma, or tissue homogenates. This assay uses the bi-antibody sandwich technique and enzyme-substrate chromogenic reaction to quantify human AST concentration. The intensity of the colored product is directly proportional to the concentration of AST present in the sample. This human AST ELISA kit has high specificity and excellent sensitivity.
AST (GOT1) is an enzyme involved in the malate-aspartate (MA) shuttle that produces cytosolic glutamate by transferring amino residue from aspartate to α-ketoglutarate. It is important for the metabolism of amino acids, Krebs cycle activity, maintenance of NAD+/NADH ratio in cells, generation of purine/pyrimidine bases, urea and protein synthesis, and gluconeogenesis. An increased AST activity may be a sign of tissue damage, plasma membrane bleb formation, enhanced tissue expression, and macroenzymes. Elevated AST levels are commonly associated with inflammatory liver disease, alcoholic liver disease, cirrhosis, cholestatic syndromes, drug toxicity, acute myocardial infarction, septic shock, and skeletal muscle injury/trauma.
There are currently no reviews for this product.
I would like to know if the kit is free of human or animal byproducts, HIV/AIDS/HCV/HBV/infectious material.
