GDF9 antibody | mAb-GDF9-53
Mouse anti Human GDF9 antibody, clone mAb-GDF9-53 recognizes an epitope within the highly conserved EPDG sequence of GDF9 (growth differentiation factor 9), a 454 amino acid ~51 kDa pro-protein which is cleaved to form a ~17.5 kDa GDF9 monomer which self associates to form an active homodimeric growth factor, a member of the TGF-beta superfamily, closely related to bone morphogenetic proteins (BMPs).
GDF9 is expressed by oocytes, playing a vital role in ovarian folliculogenesis, normal follicle development, and fertility. GDF9 signals through binding to bone morphogenetic protein type II receptor (BMPRII), and apparent subsequent activation of TGF-beta type I receptor, otherwise known as activin receptor-like kinase-5 (ALK-5).
Mouse anti Human GDF9 antibody, clone mAb-GDF9-53 recognises GDF9 with high immuno-affinity, and has been shown to neutralize GDF9 biological activity (Gilchrist et al. 2004, Dragovic et al. 2005).
Removal of sodium azide is recommended prior to use in functional assays – Bio-Rad recommend the use of EQU003 for this purpose.
