Used in biomedical research to quantify glutathione S-transferase (GST) levels in rat samples, this ELISA kit enables the detection of GST protein expression in tissue homogenates, cell lysates, and biological fluids. It is widely applied in studies related to oxidative stress, drug metabolism, and liver function, as GSTs play a key role in cellular detoxification processes. Researchers use this kit to assess the impact of toxins, pharmaceuticals, or environmental factors on the antioxidant defense system in rat models. The assay provides a sensitive and specific measurement, supporting investigations in toxicology, pharmacology, and disease biomarker discovery.
