Used in research to quantify levels of the catalytic subunit of glutamate cysteine ligase (GCLC) in mouse biological samples. This ELISA kit enables scientists to measure oxidative stress responses in cells and tissues, as GCLC is the rate-limiting enzyme in glutathione synthesis. It is widely applied in studies related to neurodegenerative diseases, liver injury, aging, and toxin exposure where glutathione metabolism plays a critical role. The assay provides a sensitive and specific method for detecting GCLC protein concentration in serum, plasma, cell lysates, and tissue homogenates, supporting both basic research and preclinical evaluation of antioxidant therapies.
