    IRR Antibody (I-63) is a mouse monoclonal IgG1 kappa light chain antibody that detects IRR protein of human origin by western blotting (WB), immunoprecipitation (IP), immunofluorescence (IF), immunohistochemistry with paraffin-embedded sections (IHCP), and enzyme-linked immunosorbent assay (ELISA). Anti-IRR antibody (I-63) is available as the non-conjugated isotype antibody. The insulin receptor-related receptor (IRR) plays a crucial role in cellular signaling pathways, particularly in insulin regulation, which is vital for maintaining glucose homeostasis in the body. Although the exact ligand for IRR remains unidentified, structural similarity to insulin and insulin-like growth factor-1 receptors suggests participation in similar signaling mechanisms. IRR is synthesized as a single polypeptide precursor that undergoes proteolytic cleavage and glycosylation, resulting in alpha and beta subunits that assemble into a heterotetramer. The two alpha subunits are responsible for ligand binding, while the beta subunits contain the kinase domain essential for downstream signaling. IRR is predominantly expressed in the kidney, with additional expression in the brain, stomach, pancreas, and heart, indicating potential involvement in various physiological processes. The gene encoding IRR is located on human chromosome 1q23.1, a region associated with type-2 diabetes mellitus, highlighting IRR′s importance in insulin signaling and metabolic regulation.

    Can sc-100303: IRR (I-63) monoclonal antibody be used to stain formalin-fixed, paraffin-embedded (FFPE) tissue sections?

    Asked by: Dr Ninau Qelp
    Thank you for your question. Yes, sc-100303: IRR (I-63) is recommended for use in IHC with paraffin-embedded sections. We recommend performing antigen retrieval with sodium citrate buffer (pH 6) and heat. The full protocol can be found here: https://www.scbt.com/scbt/resources/protocols/immunoperoxidase-staining
