Human GGCT (Gamma-glutamylcyclotransferase) ELISA Kit (HUFI04134)

Quantitative immunoassay measurement of Gamma-glutamylcyclotransferase (GGCT) in human research samples is supported by this Assay Genie microplate kit. GGCT catalyzes the cyclization of gamma-glutamyl dipeptides into 5-oxoproline and free amino acids, functioning in the downstream steps of glutathione catabolism. Published studies have linked elevated GGCT expression to bladder, breast, and non-small cell lung carcinoma, making this kit relevant for translational research into redox-pathway biomarkers in oncology workflows. The assay is intended for in vitro research use only and is compatible with standard microplate absorbance readers.

Each box ships with a pre-coated microwell plate, conjugate reagents, calibrated standards, wash buffer, and substrate solution. Researchers typically dispense a small prepared sample aliquot into each well, run the protocol at room temperature, and read absorbance at the wavelength indicated in the lot-specific data sheet. To preserve antibody activity, store kit components refrigerated and protect the conjugate vial from light until first use. The kit supports academic, clinical, and pharmaceutical laboratories studying tumor progression, the glutathione cycle, and enzyme expression patterns in patient-derived specimens.
