Immunofluorescent analysis of Insulin Receptor alpha (green) showing staining in the membrane of HepG2 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 alpha monoclonal antibody (Product # MA5-13759) 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 fluorescent red phalloidin and nuclei (blue) were stained with Hoechst or DAPI. Images were taken at a magnification of 60x.

MA5-13759 targets Insulin Receptor alpha in WB, ICC/IF, ELISA and IP applications and shows reactivity with Human samples.
The MA5-13759 immunogen is iM-9 lymphocytes followed by purified insulin receptor.
The human insulin receptor is a heterotetrameric membrane glycoprotein consisting of disulfide-linked subunits in a beta-alpha-alpha-beta configuration. The beta-subunit (95kDa) possesses a single transmembrane domain, whereas the alpha-subunit (135kDa) is completely extracellular.
