title: A new immunoreagent for cell labeling. CD3 monoclonal antibody covalently coupled to fluorescent polymethacrylic nanoparticles.
abstract: The preparation and application of immunonanospheres are described. CD3 monoclonal antibodies were covalently coupled to fluorescent polymethacrylic nanoparticles by the glutaraldehyde reaction and the resultant conjugate purified by gel filtration on a Sepharose 4B column. Peripheral blood mononuclear cells labeled with this immunoreagent were observed by both fluorescence microscopy and scanning electron microscopy in order to evaluate the technique.
