(A) Acute promyelocytic leukemia, NB-4; (B) human acute lymphoblastic leukemia (T-cell line), Molt-4; (C) human acute T cell leukemia, Jurkat; (D) human lymphoblastic leukemia (T-cell line), Sup-T1. FITC-labeled random DNA Library (Lib) and IgG-PE, which do not bind to cells, were used as negative control.
