INSR binds insulin and has a tyrosine protein kinase activity. The short isoform has a higher affinity for insulin. The receptor mediates the metabolic functions of insulin. The receptor binding to insulin stimulates association of the receptor with downstream mediators including IRS1 and phosphatidylinositol 3'-kinase (PI3K). Defects in INSR are the cause of insulin resistance.

Pathway and Disease
Each vial contains 0.1 mg of lyophilized peptide. Reconstitute with 0.1 ml deionized water for a final concentration of 1 mg/ml. Use at 5.6 ug/ml for a 100X excess over antibody for maximum blocking effect.
Insulin receptor; CD220 antigen; IR; INSR
The synthetic peptide used to raise the antibody Cat. No. 200110 is selected from a sequence within the N-term region of human INSR. For blocking experiments, a 10 to 100 fold molar excess to antibody is recommended.
Purity > 80% by HPLC
Distilled water for a solution up to 2 mg/ml, otherwise we recommend using acetonitrile.
