Anti-PSMB4 Antibody

Target the proteasome with this rabbit polyclonal antibody raised against PSMB4 (Proteasome 20S subunit beta 4), a core structural component of the 20S catalytic core complex. PSMB4 contributes to ubiquitin-dependent protein turnover and MHC class I peptide generation, making it relevant to studies of protein homeostasis, immune surveillance, and proteasome-associated disease models. Supplied at 1 mg/ml in PBS with 0.1% sodium azide and 50% glycerol, this unconjugated reagent is validated for Western blot, immunohistochemistry, and immunofluorescence workflows. The antibody recognizes the human, mouse, and rat orthologs, enabling cross-species comparison in cell and tissue samples. The 100 µl vial supports multiple staining and blotting experiments; store refrigerated and protect from light to preserve activity. From Antibodies.com, this Primary Antibodies reagent finds application in laboratories investigating proteasome biology, cancer signaling pathways, and antigen presentation mechanisms.
