Culture method

Complete Growth Medium

The base medium for this cell line is F-12K 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 are given for a 75 cm2 flask. 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 0.25% (w/v) Trypsin- 0.53 mM EDTA solution to remove all traces of serum which contains trypsin inhibitor.

3.      Add 2.0 to 3.0 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.

6.      Incubate cultures at 37°C.

Subcultivation Ratio: A subcultivation ratio of 1:3 to 1:10 is recommended

Medium Renewal:  2 to 3 times per week

Cryopreservation

Freeze medium: Complete growth medium 95%; DMSO, 5%

Storage temperature: liquid nitrogen vapor phase

Culture Conditions

Temperature: 37°C
