||Recombinant Human Growth Differentiation Factor 9 encoding the mature human Growth differentiation factor 9 (Gln320-Arg454P) was recombined with his tag at the N-Terminus. That was expressed inE.Coli, and purified by Ni-NTA column. MW=14.9KD.
||Growth/differentiation factor 9 is a protein that in humans is encoded by the GDF9 gene. Growth factors synthesized by ovarian somatic cells directly affect oocyte growth and function. Growth differentiation factor-9 (GDF9) is expressed in oocytes and is thought to be required for ovarian folliculogenesis. GDF9 is a member of the transforming growth factor-beta (TGFβ) superfamily. GDF9 plays an important role in the development of primary follicles in the ovary. It has a critical role in granulosa cell and theca cell growth, as well as in differentiation and maturation of the oocyte.
