METACHROMATIC DYE SORPTION MEANS FOR DIFFERENTIAL DETERMINATION OF SUB-POPULATIONS OF LYMPHOCYTES

摘要

Differentiation, identification and enumeration of sub-populations of lymphocytes including B-cells and T-cells can now be further discriminated into their sub-populations by means of basic orange 21 as a supravital stain to provide distinctive morphologic differences between B-cells, T-suppressor cells, T-helper cells and natural killer (NK) cells without resorting to the use of individual monoclonal antibodies for differentiation of each of the above. The differentiation, identification and enumeration of the foregoing cells can be accomplished by means of both white light absorbance and fluorescence measurements, singly or in sequential combinations.
