Cell line:K-562
DSMZ no.:ACC 10
Species:human (Homo sapiens)
Cell type:chronic myeloid leukemia in blast crisis
Origin: established from the pleural effusion of a 53-year-old woman with chronic myeloid leukemia (CML) in blast crisis in 1970; cells carry the BCR-ABL1 e14-a2 (b3-a2) fusion gene; this subclone (ACC 10) weakly expresses MHC class I (image); other subclones (ACC 86 and ACC 92) are MHC class I negative (image) and might be used in in-vitro natural killer assays; cells produce hemoglobin
Biosafety level:1
Permissions and restrictions:A
DSMZ Cell Culture Data: Morphology:round large, single cells in suspension;
