Cell Line Name


Cell Line Description

Derived from a 50 year old Japanese male with generalised lymphadenopathy and heptosplenomegaly (Adult T-cell Leukaemia) by co-culture of his peripheral leukocytes with male umbilical cord lymphocytes. The cells carry HTLV-1 and support the growth of HIV. The cells should be handled under laboratory containment level 3 conditions. STR profiling at ECACC confirms the presence of a Y chromosome

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.
