General Cell Collection: U5A

Catalogue No.: 12021506
Cell Line Name: U5A
Keywords: alpha interferon signalling pathway, IFN regulated human gene 6-16,
Cell Line Description: The human sarcoma cell line HT 1080 (ECACC Catalogue number 85111505) was transfected with a vector encoding a selectable marker (guanine phosphoribosyltransferase) regulated by alpha interferon to create the 2fTGH cell line, enabling the selection of mutations in genes encoding components of the interferon signalling pathway. Chemical mutagenesis of the parent 2fTGH cell line enabled the isolation of a number of IFNg signalling mutants available from ECACC: U2A (12021502), U3A (12021503), U4A (12021504), U4C (12021505), U5A (12021506), U6A (12021507). Each contains a different mutation in the IFN signalling pathway. The 2fTGH panel provides a tool for the in vitro study and comparison of disrupted interferon signalling at multiple points across the IFN pathway. The U5A mutant cell line lacks the ifnar2-2 component of the interferon-alpha and interferon-beta receptor and the beta-R1 gene product. U5A is completely defective in interferon alphabeta binding and response.

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. Please view the Terms & Conditions of Supply for more information.
