InVivoMAb anti-human CD220-1

InVivoMAb anti-human CD220 / Insulin Receptor (Clone IR 83-22)

The IR 83-22 monoclonal antibody reacts with human CD220, also known as insulin receptor. CD220 is a type I transmembrane receptor tyrosine kinase which, upon binding to insulin, initiates several cellular effects, including glucose uptake, cell growth, differentiation, and apoptosis. These effects primarily occur in skeletal muscle, fat, and the liver. Neuronal CD220 signaling has been shown to have an important role in energy homeostasis, reproduction, and the development of neurodegenerative diseases. The IR 83-22 antibody has been shown to inhibit approximately 80% of insulin binding to IM-9 insulin receptor expressing cells.

This antibody is useful for:

  • Flow cytometry

Bio X Cell antibodies are specifically formulated for in vivo use and feature:

  • 95% purity
