Comments: The cells are negative for Epstein-Barr virus.
Both the parental line Ramos (RA 1)細胞(ATCC CRL-1596)and the derivative cell line Ramos.2G6.4C10 (ATCC CRL-1923) have about 1500 IL-4 binding sites per cell.
The cells are reported to secrete IgM (lambda light chain).
Propagation: ATCC complete growth medium: The base medium for this cell line is ATCC-formulated RPMI-1640 Medium, Catalog No. 30-2001. To make the complete growth medium, add the following components to the base medium: heat-inactivated fetal bovine serum to a final concentration of 10%.
Temperature: 37.0°C
Subculturing: Medium Renewal: Add fresh medium every 2 to 3 days (depending on cell density)
Cultures can be maintained by the addition of fresh medium or replacement of medium. Alternatively, cultures can be established by centrifugation with subsequent resuspension at 2 X 10 exp5 viable cells/ml.
Maintain cell density between 2 X 10 exp5 and 1 X 10 exp6 viable cells/ml.
Preservation: culture medium 95%; DMSO, 5%
Related Products: Recommended medium (without the additional supplements or serum described under ATCC Medium):ATCC 30-2001
derivative:ATCC CRL-1923
