| Comments | MM.1R is resistant to dexamethasone. The closely related cell line, MM.1S (ATCC CRL-2974) was also isolated from MM.1, but is sensitive to dexamethasone. |
| Complete Growth Medium | The base medium for this cell line is ATCC-formulated RPMI-1640 Medium, ATCC 30-2001. To make the complete growth medium, add the following components to the base medium: fetal bovine serum (ATCC 30-2020) to a final concentration of 10%. |

| Subculturing |
This is a mixed cell culture; cells grow both as a lightly attached monolayer and in suspension. Cultures can be maintained by adding fresh medium. Alternatively, subcultures can be prepared by scraping the adherent cells into the medium containing the floating cells, collecting the cells by centrifugation, resuspending the cell pellet in fresh medium and dispensing into new flasks. Note: Subculture cells before they reach confluence; cells in over-confluent cultures begin to form rosettes with necrotic centers. Subcultivation ratio: A subcultivation ratio of 1:2 to 1:4 is recommended. Medium renewal: Every 2 to 3 days. |
