Anti-GDF9 Antibody

This rabbit polyclonal antibody targets Growth Differentiation Factor 9 (GDF9), a TGF-β superfamily member secreted by oocytes that governs granulosa cell signaling and early folliculogenesis. Raised in rabbit and affinity purified, the unconjugated reagent is supplied as 100 µl in a single vial and is validated for Western blot (WB) and immunohistochemistry (IHC) on human tissues, supporting reproductive biology labs profiling ovarian follicle development, granulosa cell signaling pathways, and oocyte–somatic cell cross-talk. Because the antibody is polyclonal, it recognizes multiple epitopes on the GDF9 precursor and mature region, which can be helpful when probing cleaved ligand or tissue samples where epitope accessibility varies. The unconjugated format also leaves the choice of reporter open, so researchers can pair it with HRP, biotin, or fluorophore-conjugated secondary reagents matched to their detection platform. Labs investigating oocyte-derived paracrine factors, ovarian reserve, or female fertility pathways will find this Antibodies.com reagent a focused choice for expression studies in human reproductive tissues.
