Anti-PDIA3 Antibody

PDIA3 (Protein Disulfide-Isomerase A3), also called ERp57 or GRP58, is a member of the protein disulfide isomerase family that resides primarily in the endoplasmic reticulum. This unconjugated rabbit polyclonal antibody from Antibodies.com recognizes PDIA3 across human, mouse, and rat samples and is validated for western blot, immunohistochemistry, and immunofluorescence workflows. The polyclonal format means multiple epitopes on the ~57 kDa target are recognized, which can be helpful when probing denatured or partially processed PDIA3 species.

Each tube contains 100 µL of antibody, typically used at dilutions appropriate for the application of choice. Researchers studying MHC class I antigen presentation, unfolded protein response signaling, or ER stress biology commonly use this reagent because PDIA3 functions as a thiol oxidoreductase and a component of the peptide-loading complex. Store refrigerated and protect from light to preserve activity over the recommended shelf life.
