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).
TISSUE/ORGAN: peripheral blood
TUMOR: leukemia, pre-B cell
DSMZ catalog code: ACC 20

Available in the following LABORATORY:
German Collection of Microorganisms and Cell Cultures (DSMZ, Braunschweig)
90% RPMI 1640 + 10% FBS cells are difficult to culture! cells appear to grow better in 24-well-plates than in flasks; maintain at 0.5-1.0 x 106 cells/ml; cells grow slowly, split 1:2 to 1:3 every 3-4 days; seed out at ca. 1 x 106 cells/ml at 37C with 5% CO2 maximum density at 2-3 x 106 cells/ml;
doubling time of ca. 48 hours;
frozen with 70% medium, 20% FBS, 10% DMSO at about 5 x 106 cells/ampoule;
negative in DAPI, microbiological culture, RNA hybridization, PCR assays;
Validated by: cytogenetics 1 (hyperdiploid; 47(46-48)<2n>X/XY, +mar, der(22)t(9;22)(q34;q11)) * DNA fingerprinting (unique Hinf I-(gtg)5 DNA profile) * immunological analysis (CD3- CD10+ CD13+ CD19+ CD37- HLA-DR+ cyIgG/M-) * isoenzymes (confirmed as human with IEF of G6PD, MDH, NP) * reverse transcriptase (negative)
