Comments: The cells are negative for Epstein-Barr virus. [22747]

Both the parental line （ATCC CRL-1596）and the derivative cell line Ramos.2G6.4C10 （ATCC CRL-1923） have about 1500 IL-4 binding sites per cell. [23389]

The cells are reported to secrete IgM （lambda light chain）. [1093]

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
