Anti-PSMD3 Antibody

PSMD3 (Proteasome 26S Subunit, Non-ATPase 3) is a regulatory component of the 19S proteasome cap, where it contributes to recognition and unfolding of polyubiquitinated substrates destined for degradation by the 26S proteasome. This unconjugated rabbit polyclonal antibody from Antibodies.com is raised against PSMD3 and is validated for Western blot and immunohistochemistry workflows in Human, Mouse, and Rat samples. The reagent is supplied as a 100 µl vial and enables comparative studies across common mammalian model systems investigating proteasome composition, ubiquitin–proteasome pathway activity, or protein homeostasis. Endogenous PSMD3 can be detected in cell lysates by immunoblotting and localized in fixed tissue sections, and the antibody should be aliquoted to avoid repeated freeze-thaw cycles during long-term storage.
