  • Immunohistochemistry Services

  • Work with LifeSpan to design a custom immunohistochemistry to address your specific biological question. Outsource the entire localization process without having to worry about finding and characterizing target specific antibodies, sourcing and validating difficult-to-find tissues, and having the ability to interpret the resulting immunostaining in relation to complex human pathologies.

  • TCR Screening Services

  • Test your therapeutic antibodies in immunohistochemistry against a broad panel of normal frozen human tissue types in order to determine potential unintended binding. Our non-GLP TCR services are designed on the FDA recommendation outlined in their "Points to Consider in the Manufacture and Testing of Monoclonal Antibody Products for Human Use".

Specificity and Use

GDF9 / GDF-9 antibody was raised against tuberculin coupled synthetic peptide VPAKYSPLSVLTIEPDGSIAYKEYEDMIATKC from near the C-terminal region of mature human GDF9. Percent identity by BLAST analysis: Human, Chimpanzee, Gorilla, Orangutan, Gibbon, Baboon, Monkey, Galago, Marmoset, Shrew, Bat, Dog, Armadillo (100%); Ferret, Sheep, Goat, Panda, Cat, Bovine, Pig, Opossum (97%); Mouse, Rat, Hamster, Rabbit, Horse, Turkey, Zebra finch, Chicken (94%); Elephant (90%); Guinea pig, Xenopus (81%).
Recognizes an epitope within the highly conserved EPDG sequence of GDF9 (growth differentiation factor 9), a homodimeric growth factor and member of the TGF-beta superfamily, closely related to bone morphogenetic proteins (BMPs). GDF9 is specifically 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). Clone mAb-GDF9-53 recognizes GDF9 with high immuno-affinity, and has been shown to neutralize GDF9 biological activity,. Removal of sodium azide is recommended prior to use in functional assays.

About GDF9 / GDF-9

O60383 NM_005260 NP_005251.1

GDF9 Antibody, GDF-9 Antibody

Required for ovarian folliculogenesis. Promotes primordial follicle development. Stimulates granulosa cell proliferation. Promotes cell transition from G0/G1 to S and G2/M phases, through an increase of CCND1 and CCNE1 expression, and RB1 phosphorylation. It regulates STAR expression and cAMP-dependent progesterone release in granulosa and thecal cells. Attenuates the suppressive effects of activin A on STAR expression and progesterone production by increasing the expression of inhibin B.
