Anti-GDF-9 Antibody

Raised in rabbit against human Growth Differentiation Factor 9, this polyclonal antibody recognizes the GDF9 protein, an oocyte-expressed member of the TGF-β superfamily that supports granulosa cell proliferation, cumulus expansion, and ovulation in mammals. The unconjugated reagent is supplied by Antibodies.com as a 100 µl vial and is validated for western blot and ELISA workflows across human, mouse, and rat samples, supporting reproductive biology labs studying ovarian folliculogenesis, oocyte maturation, and female fertility. Because GDF9 acts as an oocyte-secreted paracrine factor that cooperates with BMP15 during early follicle development, researchers also use the antibody to characterise knock-out ovary phenotypes and to examine granulosa cell–oocyte signalling cross-talk in both in vitro follicle culture models and in vivo ovary tissue sections. For daily handling, refrigerate the vial short term; for longer storage, keep aliquots frozen and protect from light to preserve polyclonal titer.
