Our cell lines are cryopreserved under the culturing condition designated by the depositor of each cell line. We routinely test each lot of cells using the ampoules/tubes randomly selected from a lot by thawing and culturing them for certain periods, and cryopreserve cells after confirmation that there are no problems about freeze-thaw and microbial contamination (bacteria and fungi).
