Culture Conditions

Subculture Routine

Cells are subcultured by harvesting attached and suspension cells. Remove majority of medium and centrifuge to harvest cells growing in suspension. Scrape adherent cells remaining in the flask. Resuspend cell pellet from centrifugation and combine with scraped cells. Seed into new flask at 1:3 to 1:4 split ratio i.e. seeding at 1-3 x 10,000 cells/cm² Incubate at 37°C; 5% CO₂. Please Note :- On receipt growing order cells may be in suspension. The cells and media should be removed from the flask and spun down to form a pellet. This should then be re-suspended in fresh media and a cell count performed. The cells should then be reseeded at 2-4 x 10⁴/cm and should begin to show signs of re-attachment within 48 hours.

Culture Medium

DMEM + 2mM Glutamine + 10% Foetal Bovine Serum (FBS).

Unless specified otherwise, at ECACC we routinely handle all of our cell lines at containment level 2 in accordance with the ACDP guidelines (Advisory Committee on Dangerous Pathogens) (UK). All cell cultures have the potential to carry as yet unidentified adventitious agents. It is the responsibility of the end user to ensure that their facilities comply with biosafety regulations for their own country.

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.
