Detection of Human and Mouse ERp57/PDIA3 by Western Blot.
Western blot shows lysates of HeLa human cervical epithelial carcinoma cell line, HEK293 human embryonic kidney cell line, and Hepa 1‑6 mouse hepatoma cell line. PVDF membrane was probed with 0.2 µg/mL of Sheep Anti-Human ERp57/PDIA3 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF8219) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for ERp57/PDIA3 at approximately 57 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
ERp57/PDIA3 in HeLa Human Cell Line.
ERp57/PDIA3 was detected in immersion fixed HeLa human cervical epithelial carcinoma cell line using Sheep Anti-Human ERp57/PDIA3 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF8219) at 15 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Sheep IgG Secondary Antibody (red; Catalog # NL010) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm.

ERp57/PDIA3 in Human Liver.
ERp57/PDIA3 was detected in immersion fixed paraffin-embedded sections of human liver using Sheep Anti-Human ERp57/PDIA3 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF8219) at 1 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Sheep HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS019) and counterstained with hematoxylin (blue). Specific staining was localized to the cytoplasm of hepatocytes. View our protocol for Chromogenic IHC Staining of Paraffin-embedded Tissue Sections.

ERp57 (Endoplasmic reticulum resident protein 57; also Protein disulfide-isomerase A3/PDIA3) is a 57-60 kDa member of the protein disulfide isomerase family of proteins. Knockdown of ERp57 or antibody-targeted inhibition of the secreted form significantly impaired the secretion and accumulation of extracellular matrix. ERp57 is highly similar to other PDI family members in amino acid sequence and structural/functional domain organization. This protein plays an important role in endoplasmic reticulum quality control of newly synthesized glycoproteins, is critical in major histocompatability complex class I assembly and regulates gene expression. ERp57 has been implicated in human pathologies including cancer and Alzheimer's disease. Within aa 107 - 366, human ERp57 shares 92% aa sequence identity with mouse ERp57.
