Human SPAG8 ELISA Kit (HUFI06379)

The Human SPAG8 ELISA Kit from Assay Genie enables quantitative measurement of Sperm-Associated Antigen 8 (SPAG8), a testis-enriched protein investigated in reproductive immunology and antisperm antibody research. The kit supports studies on male factor infertility, sperm antigen immunogenicity, and germ cell biology by measuring circulating SPAG8 concentrations in serum and plasma samples. Applications include investigation of idiopathic infertility, post-vasectomy antisperm responses, and autoimmune reactivity to sperm proteins. For research use only, the assay employs a human-specific capture antibody with no significant cross-reactivity with related sperm-associated antigens, providing accurate in vitro quantification for clinical and translational research.
