 Characterization of eosinophils transformed by E26 viruses coexpressing various C/EBP forms. (A) FACScan profiles of EOS47 expression (left) and peroxidase staining (right) of representative eosinophil-rich clones transformed by E26–C/EBPα, E26–C/EBPβ, and E26–βD63N viruses. Peroxidase positive cells contain dark granules. (B) Immunofluorescence (left) and combined peroxidase and DAPI staining (right) of the same field of EOS47 FACS-sorted normal chick bone marrow cells. Peroxidase-positive cells are indicated by arrows.
