Human Follistatin (FS) ELISA Kit

Follistatin is a secreted glycoprotein that binds activin and other transforming growth factor-beta superfamily ligands, regulating pathways connected to skeletal muscle development, reproductive endocrine signaling, and inflammatory balance. The Assay Genie Human Follistatin (FS) ELISA Kit enables quantitative measurement of this protein in human-derived research samples using an in vitro immunoassay workflow.

The kit supports investigation across endocrinology, reproductive biology, myogenesis research, and metabolic disorder studies, including work on polycystic ovary syndrome and age-related muscle changes. Researchers employ the assay to monitor circulating follistatin as a candidate biomarker tied to activin axis activity, gonadal function, and tissue remodeling processes.

Each kit ships with a pre-coated microplate, assay diluent, wash buffer, recombinant follistatin standards, detection antibody, and substrate solution, with a protocol requiring only a small sample volume expressed in microliters. The colorimetric readout is captured on a standard microplate reader at the wavelength detailed in the kit insert. Unopened components are stored refrigerated until first use, with working solutions freshly prepared per the enclosed protocol.
