Other Notes

Anti-IGF-I Receptor (Ab-1) Mouse mAb (αIR3) immunoprecipitates the α and β subunits of the IGF-I receptor. Blocks IGF-I binding to its receptor and may bind weakly to the insulin receptor. It also inhibits the growth of MCF-7 cells in culture suggesting the IGF-I receptor may be involved in autocrine regulation of cell growth (see application references). Antibody should be titrated for optimal results in indvidual systems.
