Anti-CST7 Antibody

Targeting human CST7 (cystatin F), this rabbit polyclonal antibody from Antibodies.com is supplied as a 50 µl aliquot and is validated for western blot detection of endogenous cystatin F protein in cell and tissue lysates. CST7 is a lysosomal cysteine protease inhibitor of the type II cystatin family that regulates granzyme B and certain cathepsins within immune effector cells, with expression most prominent in cytotoxic lymphocytes including CD8+ T cells and NK cells. The unconjugated IgG reagent also detects CST7 in select tumor models, supporting studies of immune regulation, cytotoxic granule biology, and tumor immunology. Researchers apply the antibody to standard SDS-PAGE and membrane transfer workflows, where it recognizes the full-length cystatin F glycoprotein in human samples.
