Cell Line Name


Cell Line Description

The HRA-19 cell line was established from a primary human rectal adenocarcinoma present in a 66-year old male. The adenocarcinoma was well differentiated and determined to be Dukes' stage B. The HRA-19a1.1 cell line is a clone of HRA-19. HRA-19 has stem cell properties and undergoes a multilineage differentiation in serum free medium.

If use of this culture results in a scientific publication, it should be cited in the publication as: HRA-19a1.1 (ECACC 09071517).

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.
