Immunofluorescent analysis of Insulin Receptor beta (green) showing staining in the cytoplasm of MCF-7 cells (right) compared to a negative control without primary antibody (left). Formalin-fixed cells were permeabilized with 0.1% Triton X-100 in TBS for 5-10 minutes and blocked with 3% BSA-PBS for 30 minutes at room temperature. Cells were probed with an Insulin Receptor beta monoclonal antibody (Product # AHR0271) in 3% BSA-PBS at a dilution of 1:20 and incubated overnight at 4 °C in a humidified chamber. Cells were washed with PBST and incubated with a DyLight-conjugated secondary antibody in PBS at room temperature in the dark. F-actin (red) was stained with a flourescent red phalloidin and nuclei (blue) were stained with Hoechst or DAPI. Images were taken at a magnification of 60x.

Biological actions of insulin and IGF-1 are mediated by their respective cell surface receptor tyrosine kinases that regulate multiple signaling pathways through activation of a series of phosphorylation cascades. The insulin receptor. Insulin/IGF-1 binding to the extracellular domain leads to autophosphorylation of downstream target proteins. These two receptors differ in sequence in regions that confer specificity for the designated ligand as well as in certain intracellular signaling domains, resulting in significant differences in the functional consequences of activation of each receptor. Defects in IR are the cause of various insulin resistance syndromes and IGF-1R defects may cause some forms of growth retardation. Both these signaling cascades are also important for the development of cancer.
