Human Growth Differentiation Factor 9 (GDF9) ELISA Kit

Growth Differentiation Factor 9 (GDF9) is an oocyte-derived member of the transforming growth factor-beta (TGF-β) superfamily that acts as a paracrine signal on surrounding granulosa cells to drive follicular development beyond the primary follicle stage. Mutations and altered expression of GDF9 have been implicated in primary ovarian insufficiency, polycystic ovary syndrome, and reduced female fecundity, making quantitative measurement of this factor valuable for reproductive biology, endocrinology, and infertility research.

This immunoassay kit from Assay Genie is configured for quantifying human GDF9 via a colorimetric readout on a microplate. Intended for in vitro research use only, it accepts a broad range of laboratory sample matrices, including serum samples, plasma specimens, cell lysates, tissue homogenates, and cell culture supernatants, supporting studies of follicular fluid composition, oocyte-granulosa cell crosstalk, and circulating GDF9 levels in clinical or experimental cohorts. Provided in a 96 assays kit format, the reagents are sufficient for screening multiple research samples in a single workflow, and components should be stored refrigerated until first use to preserve assay performance.
