We have used highly specific affinity-purified antibodies against mouse κ- and λ-chains in conjunction with both immunofluorescence analysis on the FACS and enzymatic radioiodination of murine splenocytes and bone marrow cells. Our results indicate that the κ/λ ratio of cell surface immunoglobulin is constant during the ontogenetic development of B cells, i.e., a shift in the κ/λ ratio does not occur during B cell maturation. Our results suggest that the events controlling κ and λ expression on murine B cells are decided very early in ontogeny, before significant antigenic selection.
