we studied the expression of an i-jk epitope on class ii-restricted cloned l3t4+ t cells established from h-2k , h-2b , f1 and semiallogeneic radiation bone marrow chimeras by the inhibition of antigen-induced t cell proliferation and in vitro secondary antibody response , and by the direct immunofluorescence with a monoclonal anti-i-jk .
