ELISA, Immunohistochemistry, Western Blot. 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.

Description
This affinity-purified antibody is directed against the phosphorylated form of human IRS1 protein at the pS307 residue. The product was affinity purified from monospecific antiserum by immunoaffinity purification. Antiserum was first purified against the phosphorylated form of the immunizing peptide. The resultant affinity purified antibody was then cross-adsorbed against the non-phosphorylated form of the immunizing peptide. Reactivity occurs against human IRS1 pS307 protein and the antibody is specific for the phosphorylated form of the protein. Reactivity with non-phosphorylated human IRS1 is minimal by ELISA. A BLAST analysis was used to suggest cross reactivity with IRS1 from human, mouse, rat, dog and vervet monkey based on 100% homology with the immunizing sequence. Partial reactivity is also expected against IRS1 from pig (94%), bovine (94%) and chicken (88%) sources. Reactivity of this antibody with IRS1 from other species is unknown.
Immunogen
This affinity purified antibody was prepared from whole rabbit serum produced by repeated immunizations with a synthetic peptide corresponding to amino acids 298-316 of human IRS1 protein.
