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: lymphoblastoid B cell
DSMZ catalog code: ACC 218
Morphology: lymphoblastoid cells growing singly and in large clumps in suspension
Description: human B-lymphoblastoid cells (from patient with melanoma) Epstein-Barr virus-positive cell line established from peripheral blood in 1977 from patient with melanoma confirmed as human with IEF of MDH, NP

Available in the following LABORATORY:
German Collection of Microorganisms and Cell Cultures (DSMZ, Braunschweig)
80-90% RPMI 1640 + 10-20% FBS maintain at about 0.3-1.0 x 106 cells/ml; optimal split ratio of 1:3 to 1:8 every 2-4 days at 37C with 5% CO2 saturation density at about 2.0 x 106 cells/ml;
doubling time of about 30-40 hours;
