Porcine Growth Differentiation Factor 9 (GDF9) ELISA Kit

Reproductive biology research in swine requires quantitative profiling of oocyte-derived signaling factors that govern folliculogenesis and ovulation rate. The Assay Genie porcine GDF9 immunoassay is configured for 96 determinations per plate and is suited to measuring endogenous growth differentiation factor 9 in ovarian follicular fluid, ovarian tissue homogenates, and cultured granulosa cell lysates collected from gilts and sows. Practical applications include tracking GDF9 expression across the estrous cycle, screening genetic variants associated with sow prolificacy and litter size, and evaluating superovulation, follicular atresia, or hormonal priming protocols. The colorimetric method is read on standard microplate readers, with absorbance values interpolated against the supplied standard curve to derive native analyte concentrations. Each kit ships with single-use vials of lyophilized standard and detection reagent; reconstituted components should be refrigerated and used within the working stability window. Researchers investigating oocyte competence, ovarian reserve, or cumulus-oocyte complex communication in pig breeding programs will find this targeted assay a practical addition to their reproductive endocrinology workflow.
