Protein production (β-galactosidase) from a baculovirus vector inSpodoptera frugiperda andTrichpolusia ni cells in suspension culture

The TN 368 cells were twice a large as Sf9 cells and appeared to be more shear sensitive than Sf7 cells, and the productivity per cell varied, from a low of 4.5×104 units in EX-CELL-400 medium to a high of 7.6× 104 units in TNM-FH.
