Virus Susceptibility Influenza A virus
Influenza B virus
Comments This cell line is susceptible to a wide range of influenza virus and is sensitive to epsilon toxin of C. perfringens.
Complete Growth Medium The base medium for this cell line is Eagle's Minimum Essential Medium. To make the complete growth medium, add the following components to the base medium: fetal bovine serum to a final concentration of 10%.
Subculturing Volumes used in this protocol are for 75 cm2 flasks; proportionally reduce or increase amount of dissociation medium for culture vessels of other sizes.
1. Remove and discard culture medium.
2. Briefly rinse the cell layer with Ca++/Mg++ free Dulbecco's phosphate-buffered saline (D-PBS) or 0.25% (w/v) Trypsin - 0.53 mM EDTA solution to remove all traces of serum which contains trypsin inhibitor.
3. Add 1.0 to 2.0 mL of Trypsin-EDTA solution to flask and observe cells under an inverted microscope until cell layer is dispersed (usually within 5 to 15 minutes).
Note: To avoid clumping do not agitate the cells by hitting or shaking the flask while waiting for the cells to detach. Cells that are difficult to detach may be placed at 37°C to facilitate dispersal.
4. Add 6.0 to 8.0 mL of complete growth medium and aspirate cells by gently pipetting.
5. Add appropriate aliquots of the cell suspension to new culture vessels. An inoculum of 1 X 104 to 2 X 104 viable cells/cm2 is recommended.
6. Incubate cultures at 37°C. Subculture when the cell concentration is between 7 X 104 and 1 X 105 cells/cm2.

Subcultivation ratio: A subcultivation ratio of 1: 2 to 1:6 is recommended.
Medium renewal: Every 2 to 3 days.

Cryopreservation Freeze medium: Complete growth medium, 95%; DMSO, 5%
liquid nitrogen vapor phase
Culture Conditions Temperature: 37°C
Atmosphere: air, 95%; carbon dioxide (CO2), 5%
Population Doubling Time approximately 22 hours
