Anti-Maspin Antibody

This rabbit polyclonal antibody targets Maspin, a serpin-family tumor suppressor encoded by the SERPINB5 gene. Maspin (Mammary Serine Protease Inhibitor) is studied for its role in regulating cell invasion, motility, and apoptosis, and its loss of expression is frequently reported in breast and prostate cancer tissue. The reagent is supplied as an unconjugated 1 mg/ml stock in PBS with 0.1% sodium azide and 50% glycerol, and the 100 µl vial is sized for routine western blot and immunohistochemistry workflows. Antibodies.com validates this polyclonal reagent on human, mouse, and rat samples, supporting cross-species tumor biology studies where SERPINB5 expression is being characterized in cultured cells, tissue sections, or whole-cell lysates.
