This is the complete description of the cell line that you selected.
By clicking on a generic term (e.g., SPECIES) you will go to the corresponding index (e.g., index of species), while by clicking on a specific term (e.g., retinoblastoma) you will go to the list of corresponding cell lines (e.g., retionoblastoma cell lines).
TUMOR: lymphoma, B cell
DSMZ catalog code: ACC 47
Morphology: cells grow as single cells or in clumps in suspension
Description: human B cell lymphoma established from the pleural effusion of a 60-year-old man with refractory immunoblastic B cell lymphoma progressed from follicular centroblastic/centrocytic lymphoma in 1990; cells were described to carry the 14;18 chromosomal translocation (bcl-2 rearranged, mbr) and to express bcl-2 mRNA confirmed as human with IEF of AST, MDH, NP
