Catalogue No.


Cell Line Name

HCT 116 BRCA2 -/- [42]

Cell Line Description

HCT 116 BRCA2 -/- [42] human colorectal carcinoma cells were generated by homologous recombination to study the role of BRCA2 in DNA repair and to identify additional functions of the BRCA2 gene. These cells show phenotypes consistent with previous reports, including loss of Rad51 foci in the presence of double-strand breaks, chromosomal rearrangements and elevated sensitivity to the DNA-damaging agents phleomycin and Parp1 inhibitors. Clone 42 was generated at the same time as clone 46 cited in Xu et al., 2014. J Pathol. 2014 Nov;234(3):386-97. The originating laboratory have advised they observed no difference in culture phenotype between clone 42 and clone 46.

HCT 116 BRCA2 -/- [42] human colorectal carcinoma cells were generated to study the role of BRCA2 in DNA repair and to identify additional functions of the BRCA2 gene. They will also be useful to identify potential therapeutic agents in cancer cells with BRCA2 mutations.

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.
