Anti-PSMA2 Antibody

PSMA2 (Proteasome Subunit Alpha Type 2), a constitutive component of the 20S proteasome catalytic core central to ubiquitin-dependent protein degradation, is targeted by this unconjugated rabbit polyclonal reagent from Antibodies.com. The antibody is calibrated at 1 mg/ml in PBS containing 0.1% sodium azide and 50% glycerol, and is validated for Western blot, immunohistochemistry, and immunofluorescence workflows across human, mouse, and rat specimens. Each vial delivers 50 µl of working stock. Investigators working on proteostasis, NF-κB signalling via IκB turnover, MHC class I antigen presentation, muscle atrophy models, or proteasome inhibitor pharmacology apply this reagent to monitor endogenous subunit expression in cell lysates, fixed tissue sections, and cultured cells. For storage, keep the vial at -20°C in single-use aliquots to limit freeze-thaw cycles and preserve binding activity. The azide-supplemented buffer permits direct use in immunostaining protocols without prior dialysis.
