The specificities of lymphocytes from peripheral blood, thymus, bursa of Fabricius and spleen were investigated according to the results in FACS analysis (fluorescence activated cell sorter) and rosette forming reaction for fed blood cells from rabbit and sheep.Anti-chicken IgG antibody labeled by FITC (fluorescein isothiocyanate; Ab-ChIgG) was employed in the present experiments.Lymphocytes from peripheral blood, bursa of Fabricius and spleen were composed of two populations, a population reacted positively with Ab-ChIgG and the other reacted negatively, but thymoctes were reacted negatively with this antibody.A part of peripheral lymphocytes from normal quail reacted positively in rosette forming reaction for rabbit red cells (RaRBC), nevertheless the lymphocytes reacted negatively in rosette forming reaction for sheep red blood cells (SRBC). However, some population of lymphocytes from quail immunized with SRBC were considered to be B cells, because they reacted positively in cell sorting by employed Ab-ChIgG and in rosette forming reaction for SRBC using as immunogen.Rosette forming cells (Ra-RFC) and non rosette forming cells (Ra-NRFC) for rabbit red cells were analysed by FACS.It was observed in results in cell sorting by FACS that the rosette forming cells for rabbit cells (Ra-RFC) showed the negative reaction for FITC labeled Ab-ChIgG, but non rosette forming cells for rabbit red cells (Ra-NRFC) the positive reaction for this antibody.Tiherf ore, it was recognized that the negative cells in cell sorting by FACS are able to be classified into two sub-populations, Ra-RFC and Ra-NRFC, or Tα sub-population and Tβ.
