Human Follistatin PharmaGenie ELISA Kit (SBRS0592)

Follistatin is a secreted glycoprotein best known for binding and neutralizing members of the TGF-β superfamily, especially activin A, myostatin, and several BMPs, which makes quantitative measurement of circulating and secreted follistatin important in studies of muscle biology, reproductive endocrinology, hepatic injury, and inflammation. This Assay Genie kit is built around a matched antibody pair immobilized on a microplate, with a biotinylated detection antibody and streptavidin-HRP reporter that produces an absorbance-based readout proportional to follistatin concentration in the well. The assay is calibrated against a recombinant human follistatin standard curve and accepts conditioned media from cultured cells, blood-derived plasma, and serum isolated from clotted samples, so the same kit can be used for myoblast or hepatocyte culture workups alongside clinical or animal-derived specimens. Each kit contains a pre-coated microplate, lyophilized standards, capture and detection reagents, wash buffer, substrate solution, and assay diluent sufficient for 96 determinations run in singlicate or duplicate. Researchers studying skeletal muscle differentiation, polycystic ovary syndrome, ovarian follicle dynamics, or acute-phase response use this kit to track how follistatin levels shift in response to hormones, exercise mimetics, or pharmacological interventions. Store unopened components refrigerated and protect the substrate from light; reconstituted standards should be aliquoted and frozen to limit freeze-thaw cycles. Intended for research use only, not for diagnostic procedures.
