Detection of Human GFER/ALR by Western Blot. Western blot shows lysates of HepG2 human hepatocellular carcinoma cell line and Hep3B human hepatocellular carcinoma cell line. PVDF membrane was probed with 2 µg/mL of Mouse Anti-Human GFER/ALR Monoclonal Antibody (Catalog # MAB7940) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF018). Specific bands were detected for GFER/ALR at approximately 20-24 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
GFER/ALR in Human Liver. GFER/ALR was detected in immersion fixed paraffin-embedded sections of human liver using Mouse Anti-Human GFER/ALR Monoclonal Antibody (Catalog # MAB7940) at 15 µg/mL overnight at 4 °C. Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using Antigen Retrieval Reagent-Basic (Catalog # CTS013). Tissue was stained using the Anti-Mouse HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS002) and counterstained with hematoxylin (blue). Specific staining was localized to cytoplasm of hepatocytes. View our protocol for Chromogenic IHC Staining of Paraffin-embedded Tissue Sections.

GFER, also known as Augmenter of Liver Regeneration (ALR) and Hepatopoietin, is an approximately 30 kDa mitochondrial sulfhydryl oxidase that plays a role in protein disulfide bond formation. Alternative splicing of human GFER generates a 15 kDa secreted isoform that lacks the 80 N-terminal amino acids. Within aa 82‑205, human GFER shares approximately 86% aa sequence identity with mouse and rat GFER. GFER protects hepatocytes from toxin-induced damage, promotes hepatic regeneration, and inhibits the metastasis of hepatocellular carcinoma. It also restricts the proliferation of pluripotent and hematopoietic stem cells and maintains mitochondrial integrity.
