Further analysis within the non-adherent leukemic cell lines KG1a (acute myelogenous leukemia, Bcl-2 +ve) [11] and Jurkat (T-cell leukemia, Bcl-2 −ve,) [12] was carried out by using the CellTiter-Blue® assay according to published precedent [5,6,7,8]. This evidence concerns the gene BCL2 and T-cell leukemia.
