Derived from pupal ovarian tissue of spodoptera frugiperda. The fall armyworm, Spodoptera frugiperda, is an important invasive pest and exhibits resistance to many insecticides. The original Sf9 cells were cloned from the parental IPLBSF-21 (Sf21) cell line that was derived from the pupal ovarian tissue of the fall army worm, Spodoptera frugiperda. Alternatively, insect cells are transfected with a recombinant bacmid DNA constructed by transposition of the donor plasmid DNA in E. coli cells, the so-called Bac-to-Bac™ (Invitrogen-Gibco/Life Technologies) method. Following the observation that control Supersomes (c-SUP) express a native … Sf9 cells are derived from pupal ovarian tissue of Spodoptera frugiperda, the Fall Armyworm. Baculovirus-infected insect cells [ Trichoplusia ni and Spodoptera frugiperda (Sf9)] are used widely for the expression of recombinant human UGT enzymes. Sf9 cells are adapted for suspension culture in ESF 921 or ESF AF and are available as a frozen vial or suspension culture.Sf9 cells are commonly used to produce recombinant baculoviral stocks and to produce recombinant proteins.

Soluble adenylyl cyclase from Spodoptera frugiperda (Sf9) cells. Scaffolds (2,396) were generated using SSPACE-LongRead (7). We have used degenerate PCR assays and massively parallel sequencing (MPS) to identify a novel RNA virus belonging to the order Mononegavirales in Sf9 cells. An insect ovarian cell, Spodoptera frugiperda (Sf9), has been widely used to express recombinant proteins, including adenylyl cyclase, as a host cell in the baculovirus expression system. The protein composition and protein changes of Spodoptera frugiperda (Sf9) cells of different infection stages were analysed by isobaric tag for relative and absolute quantification (iTRAQ) techniques.
