Product Overview
This rabbit polyclonal antibody targets proteasome subunit alpha type-1 (gene PSMA1) in human, mouse and rat samples and is validated for Western blot, IHC, flow cytometry and ELISA. The predicted molecular weight is 29.6 kDa, and the supplier reports an observed band at about 33 kDa.
PSMA1 (α6) is one of the seven α subunits that form the outer rings of the 20S core proteasome. The α rings control entry of substrates into the proteolytic chamber and dock regulatory particles such as the 19S cap, and PSMA1 is used as a marker of proteasome abundance in protein degradation research.

Immunogen
Recombinant human PSMA1 fragment (Met1–Glu252), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places proteasome subunit alpha type-1 in the cytoplasm and nucleus. The samples tested by the supplier (listed above) are a practical starting point for positive controls.

Customization & Add-ons: Can’t find the antibody you need—or require a custom format for your assay? We can help you source the best match or support custom antibody solutions for diverse research needs, including species and isotype selection, conjugations and labeling (e.g., HRP/AP, biotin, fluorophores), purification grade options (Protein A/G, affinity purified), formulation preferences (buffer selection, carrier-free, glycerol-free), custom concentrations and aliquoting, low-endotoxin options for cell-based work, and application-focused QC/validation support (project dependent).
