| Applications | The cells are positive for SV40 neo (T) antigen and SV40 transplantation antigen. |
| Storage Conditions | liquid nitrogen vapor temperature |
| Karyotype | Chromosome Frequency Distribution 49 Cells: 2n = 46 Karyotype unstable within triploid stemline range of 67 to 71. Ninety-six percent of the cells have a large chromosome with a submedian centromere. Approximately 52% of the cells have one or more secondary constrictions; 42% of the cells examined had breaks. |

| Derivation | WI-26 VA4 is an SV40 virus transformed derivative of WI-26 a human diploid fibroblast cell line from embryonic lung tissue. After initial infection and crisis-phase of SV40-transformation, the cells underwent a change in morphology. The cells are positive for SV40 neo (T) antigen and SV40 transplantation antigen. |

| Complete Growth Medium | The base medium for this cell line is ATCC-formulated Eagle's Minimum Essential Medium, Catalog No. 30-2003. To make the complete growth medium, add the following components to the base medium: fetal bovine serum to a final concentration of 10%. |
|---|---|
| Subculturing | Protocol: Remove medium, and rinse with 0.25% trypsin, 0.03% EDTA solution. Remove the solution and add an additional 1 to 2 ml of trypsin-EDTA solution. Allow the flask to sit at room temperature (or at 37C) until the cells detach. Add fresh culture medium, aspirate and dispense into new culture flasks. Subcultivation Ratio: A subcultivation ratio of 1:2 to 1:5 is recommended Medium Renewal: Twice per week |
| Cryopreservation | Freeze medium: Complete growth medium 95%; DMSO, 5% Storage temperature: liquid nitrogen vapor temperature |
| Culture Conditions | Temperature: 37.0°C |
