Adaptation of the Se301 insect cell line to suspension culture. Effect of turbulence on growth and on production of nucleopolyhedrovius (SeMNPV).

abstract：CONCLUSIONS:With the wide availability of insect cell culture media, it can generally be considered a routine process to develop new cell lines. Exceptions to this statement do exist, of course. Difficulties may arise when attempting to culture a specific cell type. For example, while there are a few cell lines from in...
