There are currently more than 100 insect cell lines available for recombinant protein production with lines derived from Bombyx mori, Mamestra brassicae, Spodoptera frugiperda, Trichoplusia ni, and Drosophila melanogaster being of particular interest.
Fall armyworm (Spodoptera frugiperda) (North and South America)
Spodoptera frugiperda cells (Sf9 and Sf21 cell lines) are commonly used in biomedical research for the purpose of recombinant protein expression using insect-specific viruses called baculoviruses.
