Immunogen Peptide sequence around AA 634-638 (P-M-S-P-K) derived from Human IRS-1. Antibodies were produced by immunizing rabbits with synthetic peptide and KLH conjugates.
Isotype IgG
Specificity The antibody detects endogenous level of total IRS-1 protein.
Purification The antibody was affinity-purified from rabbit antiserum by affinity-chromatography usingepitope-specific immunogen.
Alternative Name IRS-1 (IRS1 Antibody Abstract)
Background May mediate the control of various cellular processes by insulin. When phosphorylated by the insulin receptor binds specifically to various cellular proteins containing SH2 domains such as phosphatidylinositol 3-kinase p85 subunit or GRB2. Activates phosphatidylinositol 3-kinase when bound to the regulatory p85 subunit
Molecular Weight 180 kDa
NCBI Accession NP_005535
UniProt P35568
Pathways Fc-epsilon Receptor Signaling Pathway, EGFR Signaling Pathway, Neurotrophin Signaling Pathway
Application Notes Western blotting: 1:500-1:1000
Immunohistochemistry: 1:50-1:100
Immunofluorescence: 1:100-1:200
