RAPID QUANTITATION OF MIXED RED-CELL POPULATIONS USING FLOW-CYTOMETRY

Methods are described for the identification and quantitation of mixed red cell populations using now cytometry, Antibodies specific for a w ide range of blood group antigens have been used and examples are give n in which these analyses have proved to be of clinical use. These exa mples include monitoring of erythropoiesis following engraftment in al logeneic bone marrow transplant recipients and the detection of chimae ric states months or years after transplantation. The techniques invol ved are fast, simple and inexpensive.
