General Glutathione (GSH) ELISA Kit

This competitive ELISA from Assay Genie quantifies reduced glutathione using an absorbance-based readout in a microplate format, and is validated for universal reactivity across species commonly used in oxidative stress research. The kit measures the tripeptide's antioxidant capacity in liver homogenates, neural lysates, erythrocyte preparations, and cell culture supernatants.

Researchers typically load 50 uL of sample per well after minimal dilution, and the protocol completes within approximately 2 hours. All reagents are provided in single-use aliquot vials to minimize freeze-thaw cycles.

Unopened components should be refrigerated at 4 degrees C and protected from light; reconstituted standards remain stable for one week under refrigeration. The kit is intended for in vitro research use only and supports workflows in redox biology, toxicology screening, and nutritional studies.
