Simultaneous phenotypic and genotypic analysis on a cytospin prepared from peripheral blood cells.

Monoclonal antibody (red), PDGFβR probe (green). (A, B) CosB gave 3 hybridization signals on CD13⁺ or CD14⁺ cells, respectively, indicating the presence of the t(5;10)(q33;q22) with a split PDGFβR signal in these myeloid lineage cells. (C, D) Only 2 signals were present in the CD3⁺ or CD19⁺ cells, respectively, indicating that these lymphoid cells lack the translocation.
