Spodoptera frugiperda ( Sf9 ) cells have proved a suitable cell system in which to study this association and to produce recombinant CR3 , and we show here that another lepidopteran cell line , Trichoplusia niTN - 5B1 - 4 ( High - Five ) cells , allows the recovery of large amounts of functional recombinant CR3 .
