      | Applications | 
      The cells constitutively produce a supernatant factor(s) with growth promoting activity [PubMed: 9809582]. The 28S.3 cell line, developed in 1996, is an immortal T cell line spontaneously derived from a  long term culture of peripheral blood from a normal channel catfish.  | 
    
      
      | Storage Conditions | 
      liquid nitrogen vapor phase | 
    
      
      | Karyotype | 
      diploid | 
    
      
      | Derivation | 
      The 28S.3 cell line, developed in 1996, is an immortal T cell line spontaneously derived from a  long term culture of peripheral blood from a normal channel catfish. The cells were subsequently cloned by limiting dilution. The cells are maintained in vitro without restimulation, feeder cells, or exogenous factors.  
The cells are immunoglobulin negative [PubMed: 9809582].
The cells constitutively produce a supernatant factor(s) with growth promoting activity [PubMed: 9809582].  |

      | 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  |
