Anti-GAPDHS Antibody

This unconjugated rabbit polyclonal IgG from Antibodies.com targets GAPDHS (Glyceraldehyde-3-Phosphate Dehydrogenase, Spermatogenic), the testis-restricted glycolytic isoform that supplies ATP to the flagellum and supports sperm motility. The antibody was raised against GAPDHS and is validated for western blot, immunohistochemistry, and immunofluorescence workflows on human, mouse, and rat samples. Each vial ships as 200 µl of ready-to-titer reagent, unconjugated so it can be paired with a secondary reporter of choice for immunofluorescence or chromogenic detection in IHC. Because GAPDHS expression is largely confined to spermatogenic cells inside the seminiferous tubules, the reagent is useful for reproductive biology studies of spermatogenesis, male infertility research, and for distinguishing the germ-cell isoform from the ubiquitously expressed somatic GAPDH in tissue cross-reactivity panels. Store at -20 °C in small aliquot to limit freeze-thaw cycles and preserve polyclonal activity over multiple experiments.
