Immunogen
Aspartate Aminotransferase (AST) from Porcine Heart. Genename: GOT1
Suitable for Immunoblotting (Western or Dot blot), ELISA, Immunoprecipitation and mostimmunological methods requiring high titer and specificity. Recommended Dilutions: ELISA: 1/5,000-1/25,000. Western Blot: 1/500-1/3,000. This product has been assayed against 1.0 μg of Aspartate Aminotransferase (AST) [PigHeart] in a standard sandwich ELISA using Peroxidase conjugated Affinity Purified Goatanti-Sheep IgG [H&L] (R1364HRP) and ABTS (2,2'-azino-bis-[3-ethylbenthiazoline-6-sulfonicacid]) as a substrate for 30 minutes at room temperature. A working dilution of 1/4,000 to 1/16,000 of the reconstitution concentration is suggestedfor this product. Other applications not tested. Optimal dilutions are dependent on conditions and should be determined by the user.

Aspartate Aminotransferase [Glutamate oxaloacetate transaminase] is a ubiquitous pyridoxal phosphate-dependent enzyme which exists in both mitochondrial and cytosolic forms. The enzyme plays an important role in amino acid metabolism and in the urea and tricarboxylic acid cycles. The 2 isoenzymes are homodimeric. In liver about 80 % of the enzyme activity is mitochondrial in origin, whereas in serum the enzyme activity is largely cytosolic. Although the mitochondrial and soluble forms of GOT are coded by different chromosomes, the 2 show close homology in amino acid sequence and were presumably derived from a common ancestral gene. Serum GOT [with SGPT] levels are usually elevated in states of hepatocellular injury (injury to the liver cells), the highest levels are associated with hepatitis of a viral origin. High levels are also found after myocardial infarction, when SGPT levels are lower.Synonyms: Aspartate aminotransferase, Glutamate oxaloacetate transaminase 1, Transaminase A
