Demonstration of the cytofluorometric method on artificial mixtures of A+ and A− RBCs.
Fluorescence intensity distributions (FL1) from artificial mixtures of A+ and A− RBCs containing either: (a) 0%, (b) 50%, (c) 75%, or (d) 100% A+ cells. Genotype is defined as follows: ‘A+’ = 202C (wild-type), ‘A−’ = 202T (deficient).
