Cell Line Name

EMT6/AR1

Cell Line Description

EMT6/AR1.0 was derived from the mouse mammary tumour cell line EMT6/P (ECACC catalogue no. 96042344) by growth in increasing amounts of doxorubicin over a period of 8 weeks. The cell line showed a 40-fold greater resistance to doxorubicin, which is also known as adriamycin. The line was reported to express a classical multi-drug resistance (MDR) phenotype with hyperexpression of membrane P-glycoprotein and a spectrum of cross-resistance e.g. against vincristine and colchicine. Overexpression of CP22 (sorcin) and mdr 1a gene was reported. Cells were shown to have a reduced intracellular drug accumulation and exhibit a doubling time of 12-15 hours. It is recommended to culture the cells without drug after resuscitation until the first passage.

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.
