| 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. |
| Applications |
They are reported to secrete moderate levels of IgM in culture [PubMed: 8133033]. |
| Storage Conditions |
liquid nitrogen vapor phase |
| Karyotype |
diploid |
| Derivation |
1G8 (ATCC CRL-2756), developed in 1992, and 3B11 (ATCC CRL-2757), developed in 1994, are immortal B cell lines developed by in vitro lipopolysaccharide (LPS) stimulation of peripheral blood from two different normal channel catfish. The cells were subsequently cloned by limiting dilution. The cells are maintained in vitro without restimulation, feeder cells, or exogenous factors. They are reported to secrete moderate levels of IgM in culture [PubMed: 8133033].
The 3B11 cells constitutively express telomerase [PubMed: 11687262]. |

| Complete Growth Medium |
A 1:1 mixture of Leibovitz's L-15 medium with 2 mM L-glutamine, and AIM-V Medium adjusted to contain 1.5 g/L sodium bicarbonate and supplemented with 0.05 mM 2-mercaptoethanol, 87.5%; double distilled water, 10%; heat-inactivated Catfish serum, 2.5% (Note: The L-15 medium formulation was devised for use in a free gas exchange with atmospheric air. A CO2 and air mixture is detrimental to cells when using this medium for cultivation)
|
| Subculturing |
Protocol: 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 5 X 10(5) viable cells/ml. Interval: Maintain cell density between 5 X 10(5) and 5 X 10(6) viable cells/ml. Medium Renewal: Add fresh medium every 2 to 3 days (depending on cell density) |
| Cryopreservation |
Freeze medium: Complete growth medium supplemented with 5% (v/v) DMSO
Storage temperature: liquid nitrogen vapor phase |
| Culture Conditions |
Atmosphere: air, 95%; carbon dioxide (CO2), 5% Temperature: 27.0°C |
| Name of Depositor |
