Anti-Follistatin (R163) Antibody

This polyclonal reagent from Antibodies.com is raised in rabbit against Follistatin, a secreted glycoprotein best known for binding and neutralizing activin, myostatin, and other TGF-β superfamily ligands involved in muscle growth, reproduction, and inflammation. The antibody recognizes both full-length Follistatin and shorter circulating isoforms produced by alternative splicing and proteolytic processing.

Supplied as 100 µl of ready-to-use liquid at 1 mg/ml in PBS with 0.05% sodium azide at approximately pH 7.2, the unconjugated antibody is suitable for western blot and immunohistochemistry workflows. Validated reactivity covers human, mouse, and rat samples, supporting comparative studies of Follistatin expression across skeletal muscle, hepatic, gonadal, and reproductive tissues. The product is intended for research use only.

Aliquot and refrigerate upon receipt to preserve activity, and avoid repeated freeze-thaw cycles, which can compromise antibody performance. The reagent is shipped in a single-use vial format with handling recommendations appropriate for a protein-specific research antibody.
