Anti-GAPDHS Antibody

GAPDHS (Glyceraldehyde-3-Phosphate Dehydrogenase, Spermatogenic) is a testis-specific glycolytic enzyme that localizes to the fibrous sheath of the sperm flagellum and drives the ATP production required for progressive sperm motility. Produced in rabbit as an IgG polyclonal reagent by Antibodies.com, this unconjugated antibody is validated for Western blot, immunohistochemistry, and immunofluorescence workflows. The immunogen corresponds to a region of human GAPDHS, and the reagent has been confirmed to detect the endogenous protein in human, mouse, and rat tissue, supporting reproductive biology studies, spermatogenesis research, and investigations into male-factor infertility linked to GAPDHS loss of function. The product is supplied as a 50 µl liquid aliquot; for best results, store at -20 °C in working aliquots and limit freeze-thaw cycles to preserve binding activity.
