    Abstract:
    The kappa light chain allotypes b4 and b5 were measured in the serum and on the surfaces of peripheral blood lymphocytes of normal and allotype-suppressed heterozygous rabbits. Surface immunoglobulins (sIg) were detected by fluorescence microscopy and additional quantitative data were obtained by flow microfluorometry. Although a few b5-suppressed animals had no b5 in serum or on cell surfaces for years, most b5-suppressed and all b4-suppressed animals studied had some cells with sIg of the suppressed type by 1 year of age. In suppressed animals the level of serum Ig remained depressed throughout life but cells with sIg appeared in disproportionately large numbers. The effect was particularly striking in those animals suppressed for the b4 type.
