title: A cell-free soluble-phase radioimmunoassay for Thy-1 antigen.
abstract: A cell-free, soluble-phase, radioimmunoassay has been developed for Thy-1 antigen. The method is based on immunoprecipitation of radiolabelled Thy-1 molecules with specific antibodies, anti-immunoglobulin serum and polyethyleneglycol (PEG). The method can be used with convenience to screen for the presence of Thy-1 in various fluids as well as on cell surfaces for qualitative or quantitative purposes. Presence of antibodies or autoantibodies against Thy-1 can also be detected specifically. Evidence that the dog, carp, hamster and goldfish carry Thy-1-like molecules on neuronal (brain) cells is demonstrated by this method.
