|Culture Type:||Cell line|
|Collection:||ECACC General Collection|
|Cell Line Name:||CHO-K1|
|Other Collection No.:||ATCC CCL 61|
|Citation Guidance:||If use of this culture results in a scientific publication, it should be cited in the publication as: CHO-K1 (ECACC 85051005)|
|Keywords:||Hamster Chinese ovary|
|Cell Line Description:||A subclone of the parental CHO cell line, which was derived from the ovary of an adult Chinese hamster. Cells require proline due to the absence of the gene for proline synthesis, the block in the biosynthetic chain lies in the step converting glutamic acid to glutamine gamma serialdehyde. They undergo morphological changes in response to cholera toxin.|
|Tissue of Origin:||Ovary|
|Karyotype:||Hypodiploid, modal no. 20|
Unless specified otherwise, at the European Collection of Authenticated Cell Cultures (ECACC) we routinely handle all of our cell lines at containment level 2 in accordance with the ACDP guidelines. ACDP = 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.
