Used in research settings to detect and quantify levels of alpha-class glutathione S-transferase (α-GST) in rat biological samples such as serum, plasma, tissue homogenates, and cell lysates. This ELISA kit is particularly valuable in toxicology and pharmacology studies where α-GST serves as a biomarker for oxidative stress and cellular damage, especially in liver and kidney tissues. It enables researchers to assess organ injury, monitor the effects of drug treatments, and evaluate the impact of environmental toxins. The assay provides a sensitive and specific means to measure α-GST concentration, supporting investigations into antioxidant defense mechanisms and disease pathogenesis in rat models.
