  • Title: Antigenic properties and molecular weights of murine leukemia virus-binding proteins.
    Author: Baird SM.
    Journal: J Immunol; 1979 Apr; 122(4):1389-96. PubMed ID: 221574.
    Abstract:
    A murine T lymphoma cell line, WEHI-22, has been studied for the presence of murine leukemia virus-binding proteins and for the presence of cell surface molecules that share antigens with mouse immunoglobulins. With surface radioiodination, detergent disruption, and immunoprecipitation, a 60 to 70,000-dalton molecule has been described that is recognized by chicken anti-mouse immunoglobulin serum. In competition experiments this molecule cross-reacts with highly purified mouse IgM myeloma proteins. A cell surface molecule of similar size can be shown to bind to mouse leukemia viruses. Pre-precipitation of the WEHI-22 cell surface material with chicken anti-mouse immunoglobulin removes the material binding to leukemia viruses.
