Flow cytometry analysis of F cells in blood from two adult gg1-VP64 β-YAC bigenic mice. A sheep anti-human hemoglobin F-FITC-conjugated antibody was used to determine the percentage of HbF-expressing cells. (a) wild-type β-YAC; (b) −117 Greek HPFH β-YAC; (c) gg1-VP64 β-YAC 7; (d) gg1-VP64 β-YAC 18.
