Immunofluorescence analysis of IR/IGF1R [pYpY1162/1163] was done on 70% confluent log phase MCF7 cells treated with insulin (100nM for 5 min). The cells were fixed with 4% paraformaldehyde for 15 minutes, permeabilized with 0.25% Triton™ X-100 for 10 minutes, and blocked with 5% BSA for 1 hour at room temperature. The cells were labeled with IR/IGF1R [pYpY1162/1163] Rabbit polyclonal Antibody (44804G) at 2µg/mL in 1% BSA and incubated for 3 hours at room temperature and then labeled with Alexa Fluor 488 Goat Anti-Rabbit IgG Secondary Antibody (A11008) at a dilution of 1:400 for 30 minutes at room temperature (Panel a: green). Nuclei (Panel b: blue) were stained with SlowFade® Gold Antifade Mountant DAPI (S36938). F-actin (Panel c: red) was stained with Alexa Fluor 594 Phalloidin (A12381). Panel d is a merged image showing membrane localization. Panel e shows untreated MCF7 cells. Panel f shows no primary antibody control. The images were captured at 20X magnification.

IGF-1R (Insulin-like Growth Factor-1 Receptor) consists of alpha- and beta-subunits, which are disulfide-linked in a beta-alpha-alpha-beta configuration in the mature receptor. The alpha-subunit is completely extracellular, while the beta-subunit spans the membrane and the intracellular portion has intrinsic tyrosine kinase activity.
