Supplier: Rockland

Purpose: IRS1 phospho S307 Antibody

Cross-Reactivity (Details): This affinity-purified antibody is directed against the phosphorylated form of human IRS1 protein at the pS307 residue.

Characteristics: Synonyms: rabbit anti-IRS1 pS307 antibody, IRS-1, IRS 1, HIRS 1 antibody, HIRS-1 antibody, Insulin Receptor Substrate 1 antibody

Purification: The product was affinity purified from monospecific antiserum by immunoaffinity purification.

Sterility: Sterile filtered

Immunogen:

Immunogen: This affinity purified antibody was prepared from whole rabbit serum produced by repeated immunizations with a synthetic peptide corresponding to an internal region near amino acids 290-320 of human IRS1 protein.

Immunogen Type: Conjugated Peptide

Isotype: IgG

Application Details

Application Notes:

Immunohistochemistry Dilution: User Optimized

Application Note: This affinity purified antibody has been tested for use in ELISA and western blot.  Specific conditions for reactivity should be optimized by the end user. Expect a band approximately 130 kDa in size corresponding to phosphorylated IRS1 protein by western blotting in the appropriate cell lysate or extract.   Minimal reactivity is observed against the non-phosphorylated form of the immunizing peptide.  This antibody is phospho specific for pS307 of IRS1 protein.

Target Details for IRS1

Target: IRS1 (Insulin Receptor Substrate 1 (IRS1))

Alternative Name: IRS1

Background: Background: Insulin Receptor Substrate 1 (IRS1) acts as a signaling molecule for IL-4, insulin and insulin-like growth factor-I (IGF-I) receptors.  When phosphorylated by the insulin receptor, IRS1 binds specifically to various cellular proteins containing SH2 domains such as phosphatidylinositol 3-kinase p85 subunit or GRB2.  When bound, IRS1 typically activates phosphatidylinositol 3-kinase p85 subunit.  IRS1 interacts with both the NPXY motif of tyrosine-phosphorylated IGF1R and the INSR through the PTB domain.  Serine phosphorylation of IRS1 is a mechanism for insulin resistance. Diseases associated with IRS1 include Diabetes Mellitus, Noninsulin-Dependent and Mixed Cell Adenoma. Anti-IRS1pS307 is useful for researchers interested in protein kinase binding, IL-2 pathways, and RET signaling.
