Membrane-associated immunoglobulin of rabbit peripheral blood lymphocytes: allelic exclusion at the b locus.

Light chain allotypic determinants were demonstrated on the surface of peripheral blood lymphocytes of rabbits. By means of a combined immunofluorescent and autoradiographic technique, a great majority of the individual lymphocytes of rabbits heteroxygous at the b locus were shown to have detectable quantities of only one allotype. A small proportion of lymphocytes appeared to possess both allelic forms of L chains.
