Subculture Routine

If starting from a frozen ampoule the cryoprotectant should be removed. Add thawed cells to a conical based centrifuge tube e.g. 15ml tube; slowly add 4 ml of culture medium to the tube. Take a sample of the cell suspension, e.g. 100µl, to count cells. Centrifuge the cell suspension at low speed i.e. 100 - 150 x g for a maximum of 5 minutes. Remove medium and resuspend the cell pellet at a density of 5 x 100,000 cells/ml in fresh medium containing 20% serum. Incubate flask at 37°C; 5 - 7% CO₂. Check daily. Keep flask in a vertical position until the cells reach the exponential phase of growth. This can take up to 7 days. Once the culture is established the serum concentration can be reduced to 10%.Maintain cultures between 5 - 20 x100,000 cells/ml by splitting saturated cultures 1:2 every 2-4 days; 5% CO₂; 37°C. Doubling time approximately 60-90 hours. Round polygonal cells growing singly or in small clusters in suspension.

Culture Medium

RPMI 1640 + 2mM Glutamine + 20% Foetal Bovine Serum (FBS).

The Culture Collections represent deposits of cultures from world-wide sources. While every effort is made to ensure details distributed by Culture Collections are accurate, Culture Collections cannot be held responsible for any inaccuracies in the data supplied. References where quoted are mainly attributed to the establishment of the cell culture and not for any specific property of the cell line, therefore further references should be obtained regarding cell culture characteristics. Passage numbers where given act only as a guide and Culture Collections does not guarantee the passage number stated will be the passage number received by the customer.

Cultures supplied by Culture Collections are for research purposes only. Enquiries regarding the commercial use of a cell line are referred to the depositor of the cell line. Some cell lines have additional special release conditions such as the requirement for a material transfer agreement to be completed by the potential recipient prior to the supply of the cell line.
