| Derivation： | The Farage cell line was adapted to culture in 1990 from a lymph node biopsy of a patient with diffuse large cell non-Hodgkins lymphoma (DLCL). |
| Clinical Data： | adult

| Antigen Expression： | CD10 +/-; CD11a + (LFA-1); CD19 +; CD20 +; CD21 +; CD22 +; CD23 +; CD29 (VLA-4) +; CD38 +; CD39 +; CD40 +; CD44 +; CD54 + (ICAM-1); CD58 + (LFA-3); CD23 -; HLA DR + |
| Comments： | The cells do not express surface or cytoplasmic immunoglobulin.
Exposure to IL-4 augmented the concentrations of CD23, CD54, and CD58 but diminished the expression of CD21, CD22, and CD38. Incubation with IL-4 for 6 to 8 days led to increased expression of CD11a, CD39, CD40, and to disappearance of CD21 and CD38. Exposure of Farage cells to phorbol 12-myristate 13-acetate (PMA) down-regulated CD21 and CD23 expression.
They do not express the terminal deoxynucleotydyl transferase gene (TdT), nor the recombination activating genes RAG-1 and RAG-2, known as markers of the pre-B cell stage. These results show that Farage represents a mature B-cell rather than a pre-B cell. The cells are positive for Epstein-Barr virus (EBV).

| 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： | 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 3 - 5 x 105 viable cells/mL. Maintain cell density between 3 x 105 and 3 x 106 viable cells/mL. Medium Renewal: Add fresh medium every 2 to 3 days (depending on cell density). |
| Cryopreservation： | culture medium 95%; DMSO, 5% |
| Culture Conditions： | Temperature: 37°C |
