Cell Line Name

TRA-171

Cell Line Description

The cell line TRA-171 has been established from freshly hatched larvae of Toxorhynchites amboinensis. After eggs had been surface-sterilised, they were allowed to hatch in MM / VP12 medium and were mechanically damaged at the anterior or posterior ends of the body in 0.05% trypsin. After washing and cultivation at 22 - 25°C small patches of cells were visible leading to the isolation of the cell line TRA-171 after 72 days in culture. The cells have been adapted to grow in a 1:1 mixture of Leibovitz L-15 and Mitsuhashi and Maramorosch media plus supplements. Four serotypes of laboratory adapted and three type strains (1, 2 and 3) of un-adapted dengue virus will replicate in the cells at 28°C.

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.
