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 alpha-subunits (135 kDa) and beta-subunits (95 kDa) that are cleaved products of a common precursor. The 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.

Reviews
What customers say
Reviews are mixed. One user reported strong, reliable signals in human white adipocytes by immunofluorescence at 1:500. Another found it functional for Western blot in mesenchymal stem cells but noted three bands. A third user was critical, stating the antibody detected a ~180 kDa band (PNGaseF-sensitive, EndoH-resistant) far larger than the expected InsR size; after stripping and re-probing with a different InsR antibody, the correct molecular weight appeared, suggesting this antibody may recognize a non-specific target. Overall, results vary by application and sample.
The reviews below have been submitted by verified Proteintech customers who received an incentive for providing their feedback.
Mi (Verified Customer) (05-29-2023) | It works well in human white adipocytes, we get strong signals
|
Chiara (Verified Customer) (10-04-2021) | Works well but three bands
|
Boyan (Verified Customer) (06-06-2021) | 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.
