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.

Background: ERp57/PDIA3

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.
