Anti-PSME2 Antibody

Polyclonal antibody targeting PSME2 (proteasome activator subunit 2, also called PA28β), the inducible beta subunit of the 11S regulatory complex that binds the 20S core proteasome and shapes MHC class I antigen processing in vertebrate cells. Raised in rabbit and supplied as an unconjugated reagent at 1 mg/ml in PBS with 0.1% sodium azide and 50% glycerol, this Antibodies.com preparation is packaged in a 100 µl vial sized for routine western blot and immunohistochemistry workflows.

Validated for human, mouse, and rat samples, the reagent is commonly applied to studies of ubiquitin–proteasome signalling, immunoproteasome assembly, and stress-related changes in proteolytic activity in cancer, neurodegeneration, and viral infection models. Storage at -20°C in working aliquots is recommended to limit freeze-thaw cycling of the glycerol-containing buffer; keep the vial protected from light during use.

Provided as a primary antibody for research use only, intended for investigators examining proteasome regulation, antigen presentation pathways, and downstream cellular responses to altered PSME2 expression.
