Anti-PSMA3 Antibody

This rabbit polyclonal antibody targets PSMA3 (Proteasome Subunit Alpha Type 3), a core component of the 20S proteasome catalytic complex responsible for ubiquitin-dependent protein degradation in eukaryotic cells. Raised in rabbit and supplied as an unconjugated reagent, the antibody is validated for western blot, immunohistochemistry, and immunofluorescence workflows, making it a useful reagent for studies of proteasome biology, cellular protein turnover, and stress-response pathways.

Cross-species reactivity covering human, mouse, and rat samples allows investigation of proteasome subunit expression in tissue sections and cultured cells alike. The reagent is provided in a 100 µl volume suitable for multiple staining or blotting runs. Researchers studying oncology, neurodegeneration, and immune regulation frequently pair anti-PSMA3 reagents from Antibodies.com with downstream detection chemistries to probe 20S proteasome assembly and subunit composition.
