Insulin-like growth factor receptor 1 (IGFR1) is a tyrosine kinase receptor that is important in embryonic development. IGFR1 has effects in breast, prostate, gastric and lung cancers, as it can be a player in drug resistance. It also affects the flow of nutrients from mother to placenta to fetus during development. IGFR1 seems to greatly influence the rate of growth of fetuses and newborn babies; when it is not appropriately expressed or regulated, fetal growth restriction occurs. The major activity of IGFR1 is to mediate the signaling of growth signals to effect downstream growth patterns.

FAQs for IGF-I R Antibody (NBP1-77679). (Showing 1 - 1 of 1 FAQ).

  1. Our customer would like to perform IHC with samples from Rat. She has questions regarding antibodies of choice: 1. Is it possible to use NB400-142 for IHC? 2. I am having difficulty of choosing between NBP1-77679 and NBP1-77680. Would you please help suggest? 3. Although it is described as IHC (-) on the product page of NBP1-07034, This antibody did not work in IHC with mouse tissue is also described. How about Rat samples? Is it possible that the antibody can work in IHC with rat tissues?
    • To answer your questions about NB400-142, this antibody has not been validated for IHC and we cannot guarantee that it will work. Both NBP1-77679 and NBP1-77680 have been validated for use in rat and IHC. The difference between these 2 antibodies is the immunogen as they were raised against different regions of the protein. Please point out the immunogen to your customer and have them decide what would be best for their research. NBP1-07034 does not work in IHC, it is only guaranteed for Western blot in human, mouse and rat. When an application is followed by a (-) I would not recommend using this application in any species.
