The antibody detects endogenous levels of IRS-1 only when phosphorylated at serine 312.
Purification
The antibody was affinity-purified from rabbit antiserum by affinity-chromatography using epitope-specific phosphopeptide. The antibody against non-phosphopeptide was removed by chromatography using non-phosphopeptide corresponding to the phosphorylation site.
Immunogen
Peptide sequence around phosphorylation site of pSer312 (A-T-S (p) -P-A) derived from Human IRS-1. Antibodies were produced by immunizing rabbits with synthetic peptide and KLH conjugates.

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
