Effect of low inoculation density in the scale-up of insect cell cultures.

The scale-up of insect cell cultures and the production of baculovirus with these cultures is dependent on the inoculation density applied. The effect of applying a low inoculation on the specific growth rate and on the duration of the lag phase was tested. Three different cell lines, HzAm1, Ha2302, and Sf21 were tested in a total of five cell line/medium combinations.
