Background Information

The biological effects of INS are mediated by a membrane spanning cell surface receptor that has been shown to consist of disulfide-linked 135-kDa and 95-kDa alpha- and beta-subunits that are cleaved products of a common precursor. Binding of INS to the receptor extracellular domain results in intracellular activation of a tyrosine-specific kinase activity and the generation of signals that determine the cellular response (PMID: 2369896). This antibody raised against 980-1382aa of human INS receptor can recognize full-length INS receptor precursor and INS receptor beta subunit.

This antibody recognized a band at ~ 180 kd only, which is sensitive to PNGaseF, but not EndoH, treatment. The size is much bigger than an expected InsR band. Importantly, stripping the membrane and re-blot with another InsR antibody from a different brand could detect the protein at the expected MW. These results suggest this InsR antibody is detecting something other than InsR.
