Split sub-confluent cultures (70-80%) 1:3 to 1:6 i.e. seeding at 2-4x10,000 cells/cm² using 0.05% trypsin or trypsin/EDTA; 5% CO2; 37°C.
C70 cells grow very slowly (see growth curve); following resuscitation or subculture the cells take at least 48 hours to re-attach. Cells should be left without disturbance during this time to facilitate adhesion. Centrifugation of the cells (100g x 5 min) at resuscitation to remove DMSO improves the establishment of a viable culture. Once attached, the cells grow in discrete islands and use of trypsin or trypsin/EDTA to subculture the cells (even without knocking the flask) yields large clumps. Further disaggregation may be achieved by repeatedly pipetting the cells. >

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.
