Background information
In peripheral blood, the CD123 antigen is expressed at high levels only on plasmacytoid dendritic cells and basophilic granulocytes. By contrast, monocytes, eosinophilic granulocytes, myeloid dendritic cells, and subsets of hematopoietic progenitor cells express CD123 only at low levels.
Applications
Positive selection of human basophilic granulocytes and plasmacytoid dendritic cells.
