|---|---|
| 商品货号： | TS211038 |
| Organism： | Homo sapiens, human |
| Cell Type： | B lymphocyte |
| Product Format： | frozen |

Biosafety classification is based on U.S. Public Health Service Guidelines, it is the responsibility of the customer to ensure that their facilities comply with biosafety regulations for their own country. |
| Disease： | Burkitts lymphoma (American) |
| Age： | 3 years |
| Gender： | male |
| Ethnicity： | Caucasian |
| Applications： | Ramos.2G6.4C10 cells provide a sensitive and specific assay system for IL-4 that is insensitive to the presence of other lymphokines and cytokines such as interleukins (IL-2, IL-2 and IL-6), colony stimulating factors (G-CSF, M-CSF and GM-CSF) and interferons alpha and gamma (IFN alpha, IFN gamma). Tumor necrosis factors alpha and beta (TNF alpha, TNF beta) cause only minor interference.
The assay is sensitive to IL-4 concentrations in the range 50 to 800 pg/mL. |
| Storage Conditions： | liquid nitrogen vapor phase |
| Derivation： | This line was derived from the Ramos (RA-1) cell line (see ATCC CRL-1596) by repetitive cloning with selection for low constitutive expression of CD23 and maximum stimulation of CD23 expression by IL-4. |
| Clinical Data： | 3 years Caucasian male |
| Antigen Expression： | CD23 + |
| Receptor Expression： | interleukin 4 (IL-4); low affinity IgE (CD23) |
| Genes Expressed： | immunoglobulin (surface and secreted) |
| Cellular Products： | immunoglobulin (surface and secreted) |
| Comments： | Both the parental line (ATCC CRL-1596) and the derivative cell line Ramos.2G6.4C10 (TS211038) have about 1500 IL-4 binding sites per cell.
|
| 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 addition or replacement of fresh medium. Establish new cultures at 5 x 10 5 viable cells/mL and maintain between 1 and 2 x 10 6 cells/mL.
Medium Renewal: Add fresh medium every 4 to 6 days (depending on cell density) |
| Cryopreservation： | Freeze medium: Complete growth medium, 92.5%; DMSO, 7.5% Storage temperature: liquid nitrogen vapor temperature |
| Culture Conditions： | Temperature: 37°C |
| STR Profile： | Amelogenin: X CSF1PO: 10,11 D13S317: 13 D16S539: 10,13 D5S818: 7,12 D7S820: 11 THO1: 7,9.3 TPOX: 8,9 vWA: 15,16 |
| Isotype： | IgM |
| Name of Depositor： | JP Siegel |
| Deposited As： | Homo sapiens |
