Anti-PSME2 Antibody

This unconjugated rabbit polyclonal reagent from Antibodies.com recognizes PSME2, the proteasome activator subunit 2 (also known as PA28β or REG-β). PSME2 forms a heteroheptameric ring with PSME1 that caps the 20S proteasome and modulates MHC class I antigen processing in the cytosol and nucleus. The antibody is raised in rabbit hosts and validated for Western blot and immunohistochemistry workflows across human, mouse, and rat samples, making it suitable for comparative studies of immunoproteasome regulation. Supplied as 100 µl of polyclonal antiserum in a single vial, the reagent supports detection of endogenous PSME2 expression in cell and tissue lysate preparations.
