Human Glutathione S Transferase Alpha 4 (GSTa4) ELISA Kit

For laboratories investigating oxidative-stress biology and xenobiotic detoxification, this immunoassay from Assay Genie supplies reagents for quantifying Glutathione S-Transferase Alpha 4 (GSTa4) in human specimens. The alpha-class isoenzyme GSTa4 displays the highest catalytic efficiency for conjugating 4-hydroxynonenal, a reactive aldehyde produced when polyunsaturated membrane lipids undergo peroxidation. Because circulating concentrations of the enzyme rise in proportion to cumulative oxidative load, the assay supports research into chemical toxicology, hepatocellular injury, and disease mechanisms linked to reactive oxygen species. Reagents are provided as single-use aliquots for direct addition to the wells of an included microplate, and the kit is supplied in a sealed pack of 96 assays formatted for moderate-throughput screening. The colorimetric endpoint is captured on a standard absorbance plate reader, removing the requirement for fluorescence or luminescence instrumentation. Store the unopened kit refrigerated and equilibrate all components to room temperature before initiating the protocol; the workflow is intended for research use only and for in vitro examination of human-derived material.
