Cell Line Name


Cell Line Description

COS-1 cell line (ECACC catalogue no. 88031701) adapted to grow in the chemically defined protein- and peptide-free InVitrus medium (Cell Culture Technologies). This cell line is substrate dependent i.e. adherent. COS-1 was derived from CV-1 simian cells transformed by origin-defective mutant of SV40 which codes for wildtype T Ag. Possible host for propagation of pure populations of recombinant SV40 virus. The cells should be handled under laboratory containment level 2.

Culture Conditions

Cell Type


Subculture Routine

In order to prevent syncitia formation, do not allow cells to become confluent. Split semi-confluent cultures 1:3 i.e. seeding at 4x10,000 cells/cm² using an animal component free dissociation reagent; incubate at 37°C. Please note: Once cells have detached from the flask it is necessary to neutralise the dissociation reagent using a compatible inhibitor . Centrifuge the cells; 100-150 x g for 3-5 minutes; count and re-suspend at the recommended seeding density in fresh medium

Culture Medium

InVitrus medium (Cell Culture Technologies + 4mM Glutamine + 5 ug/ml Insulin. When freezing cells down use 50:50 fresh culture medium:conditioned medium plus 10% DMSO.

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.
