| Culture Properties： | Suspension |
| Biosafety Level： | 1
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. |
| Strain： | Lewis (B cell); BALB/c (myeloma) |
| Applications： | The antibody profoundly blocks antigen specific murine class II MHC antigen reactive helper T lymphocyte lines. |
| Storage Conditions： | liquid nitrogen vapor phase |
| Derivation： | Animals were immunized with the cloned cytotoxic T lymphocyte lines V4 and 243/2.5. Spleen cells were fused with Sp2/0-Ag14 myeloma cells. |
| Genes Expressed： | immunoglobulin; monoclonal antibody; against mouse helper, inducer T cells (L3T4 antigen, CD4) |
| Cellular Products： | immunoglobulin; monoclonal antibody; against mouse helper, inducer T cells (L3T4 antigen, CD4) |
| Comments： | L3T4 is expressed on mouse helper/inducer T cells and is analogous to the human Leu-3/T4 molecule. Tested and found negative for ectromelia virus (mousepox). |
| Complete Growth Medium： | The base medium for this cell line is ATCC-formulated Iscoves Modified Dulbeccos Medium, Catalog No. 30-2005. To make the complete growth medium, add the following components to the base medium: fetal bovine serum to a final concentration of 20%.
|
| Subculturing： | Cultures can be maintained by addition of fresh medium. Alternatively, cultures can be established by centrifugation with subsequent resuspension at 1 x 105xa0viable cells/mL. Maintain cultures at a cell concentration between 1 x 105 and 1 x 106xa0cells/mL. Do not allow the cell concentration to exceed 1 x 106xa0cells/mL.
Medium Renewal: Every 2 to 3 days |
| Cryopreservation： | Complete growth medium supplemented with 5% (v/v) DMSO.xa0Cell culture tested DMSO is available as ATCC Catalog No. 4-X.
|
| Culture Conditions： | Temperature: 37°C
Atmosphere: Air, 95%; Carbon dioxide (CO2), 5% |
| Isotype： | Rat IgG2b |
| Name of Depositor： | FW Fitch |
| Deposited As： | rat (B cell); mouse (myeloma) |
