Human GPX5 ELISA Kit (HUFI04039)

Glutathione peroxidase 5 (GPX5) is a selenium-independent antioxidant enzyme expressed predominantly in the caput epididymidis of the male reproductive tract, where it protects maturing spermatozoa from lipid peroxidation damage during post-testicular transit. Loss or reduction of GPX5 expression has been linked in the literature to compromised sperm motility, DNA fragmentation, and idiopathic male infertility. The Assay Genie human GPX5 ELISA kit provides a quantitative immunoassay for measuring GPX5 protein concentrations in human research samples, supporting studies of male reproductive biology, oxidative-stress biomarkers, and andrology. The kit includes pre-coated microplate wells and all reagents needed to complete 96 Assays, intended for research use only. Components should be refrigerated upon arrival to preserve antibody binding activity and recombinant standard stability until first use. Investigators examining antioxidant defenses in the epididymis, varicocele-associated oxidative stress, or outcomes of assisted reproduction can pair the ELISA with western blot or immunohistochemistry to validate GPX5 expression across target tissues and secretions.
