Human SPAG4 ELISA Kit (HUFI06376)

SPAG4 (Sperm Associated Antigen 4) is a protein predominantly expressed in the testis and associated with sperm development and male germ cell function. The Assay Genie human SPAG4 ELISA Kit enables quantitative measurement of SPAG4 levels in human research specimens, supporting laboratory investigations into spermatogenesis, idiopathic male infertility, and the cellular biology of male germ cells. The kit is supplied in a microplate format configured for research use only, with all buffers, standards, and detection reagents required to run the standard curve alongside experimental samples. Store unopened components refrigerated and protect from light until first use; allow sealed plates and reagents to equilibrate to room temperature before initiating the protocol. Each lot is validated by the manufacturer to confirm inter-assay consistency. Intended strictly for laboratory research applications, the assay is not cleared for clinical diagnostic use.
