in the present study we show that when murine c57bl/6 spleen cells were sorted by flow cytometry into fractions positive or negative for qa-5 , ly-2.2 , thy-1.2 , l3t4 , or surface immunoglobulin ( sig ) and for high or low expression of h-2kb , the pattern of nc activities was quite different from the negative selection experiments with antibody and complement .
