Product details:
Rat AST ELISA Kit (Aspartate Aminotransferase) (ab263883) is a single-wash 90 min sandwich ELISA designed for the quantitative measurement of AST (Aspartate Aminotransferase) protein in cit plasma, edta plasma, hep plasma, and serum. It uses our proprietary SimpleStep ELISA® technology. Quantitate Rat AST (Aspartate Aminotransferase) with 42.4 pg/ml sensitivity.
SimpleStep ELISA® technology employs capture antibodies conjugated to an affinity tag that is recognized by the monoclonal antibody used to coat our SimpleStep ELISA® plates. This approach to sandwich ELISA allows the formation of the antibody-analyte sandwich complex in a single step, significantly reducing assay time. See the SimpleStep ELISA® protocol summary in the image section for further details. Our SimpleStep ELISA® technology provides several benefits:
- Single-wash protocol reduces assay time to 90 minutes or less
- High sensitivity, specificity and reproducibility from superior antibodies
- Fully validated in biological samples
- 96-wells plate breakable into 12 x 8 wells strips
A 384-well SimpleStep ELISA® microplate (
ab203359
) is available to use as an alternative to the 96-well microplate provided with SimpleStep ELISA® kits.
Cytoplasmic aspartate aminotransaminase (AST), is a key enzyme in the regulation of glutamate levels. It catalyzes the reversible transfer of an a-amino group between aspartate and glutamate. Given its central role in amino acid metabolism, it plays a critical role in many biological functions. In a clinical context, AST levels in the serum are used as a marker for liver health. This kit targets the full-length protein.

Aspartate Aminotransferase (AST) also known as aspartate transaminase or aspartate transferase is an enzyme important for amino acid metabolism. Mechanically it catalyzes the reversible transfer of an amino group from aspartate to α-ketoglutarate forming oxaloacetate and glutamate. AST has a molecular mass of approximately 92 kDa and is expressed in various tissues with high levels found in liver heart muscle and kidneys. Its presence in these tissues highlights its importance in cellular metabolic processes.
Biological function summary
AST facilitates the interconversion between aspartate and oxaloacetate playing a role in the amino acid and urea cycles. Though not part of a large complex AST works closely with similar enzymes such as alanine aminotransferase (ALT) to maintain amino acid balance and support energy production. This enzymatic activity is important in nitrogen metabolism and glutamate use which are necessary for synthesizing other essential molecules within the cell.
Pathways
AST participates in the citric acid cycle and malate-aspartate shuttle enabling efficient energy production and NADH transport. The enzyme assists in converting oxaloacetate a pivotal intermediate in the citric acid cycle to keep the cycle active ensuring efficient cellular respiration. Additionally in the malate-aspartate shuttle AST works alongside malate dehydrogenase to facilitate the transfer of reducing equivalents across the mitochondrial membrane which is essential for ATP generation.
Elevated AST levels often indicate liver damage such as in hepatitis or cirrhosis reflecting its significant tissue expression. The enzyme is also linked to myocardial infarction as damaged heart muscle releases AST into the bloodstream. In these conditions AST serves as a biomarker for tissue damage often in conjunction with ALT levels allowing clinicians to assess the extent of liver or cardiac injury.
