Detection of Human, Mouse, and Rat IRS1 by Western Blot. Western blot shows lysates of MCF-7 human breast cancer cell line, HepG2 human hepatocellular carcinoma cell line, C2C12 mouse myoblast cell line, and PC-12 rat adrenal pheochromocytoma cell line. PVDF membrane was probed with 1 µg/mL of Goat Anti-Human/Mouse/Rat IRS1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3978) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF017). A specific band was detected for IRS1 at approximately 170 kDa (as indicated). This experiment was conducted using Immunoblot Buffer Group 1.

IRS1 in Human Liver Cancer Tissue. IRS1 was detected in immersion fixed paraffin-embedded sections of human liver cancer tissue using Goat Anti-Human/Mouse/Rat IRS1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3978) at 15 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue). Specific staining was localized to cytoplasm.

Background: IRS1

IRS1 (Insulin Receptor Substrate 1) is a cytoplasmic protein that participates in the insulin signaling pathway. It is phosphorylated by the insulin receptor upon binding of insulin and subsequently associates with several SH2-domain-containing proteins.
