The rosette formation of lymphocytes with sheep red blood cells is obvious however the rosette forming percents of lymphocytes is rather low,lower than 2%. The cross reactivity of lymphocytes with monoclonal antibody against human CD showed that there are 5.25%+0.38% of NK cells in peripherial lymphocytes of Paralichthys oliveaceus,and the CD25^+ percentage of lymphocytes is 5.25%+0.38%.No cross-reactivity with T-cell antigen,B-cell antigen and other activity antigen is found on the lymphocytes surface of Paralichthys oliveaceus.展开更多
