About InVivoMAb rat IgG2b isotype control, anti-trinitrophenol-keyhole limpet hemocyanin The TNP-4G1 monoclonal antibody reacts with trinitrophenol (TNP) hapten conjugated to keyhole limpet hemocyanin (KLH) protein. Because TNP-KLH is not expressed by mammals this antibody is ideal for use as an isotype-matched control for rat IgG2b antibodies in most in vivo and in vitro applications.
