The Spodoptera frugiperda Sf9 cell line is a heterogeneous population of rhabdovirus-infected and virus-negative cells: Isolation and characterization of cell clones containing rhabdovirus X-gene variants and virus-negative cell clones We declare no conflicts of financial or personal interest. Accumulating evidence indicates that several human UDP-glucuronosyltransferase (UGT) enzymes catalyze both glucuronidation and glucosidation reactions. The Sf9 cell line, derived from Spodoptera frugiperda, is used as a cell substrate for biological products, and no viruses have been reported in this cell line after extensive testing. Sf9 cells, a clonal isolate of Spodoptera frugiperda Sf21 cells (IPLB-Sf21-AE), are commonly used in insect cell culture for recombinant protein production using baculovirus.They were originally established from ovarian tissue.

Manassas, VA). %PDF-1.5 Among insect cells, the Sf9 cell line from Spodoptera frugiperda is the most extensively used platform. Abstract. We used degenerate PCR assays and massively parallel sequencing (MPS) to identify a novel RNA virus belonging to the order Mononegavirales in Sf9 cells. Spodoptera frugiperda cell lines and their derivatives are used to produce a variety of baculovirus-expressed biological products. The Sf9 cell line was cloned from the parent Sf21 cell line (IPLB-Sf-21-AE), which was derived from pupal ovarian tissue of the fall armyworm (Spodoptera frugiperda) . 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.

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. 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. 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.

Accumulating evidence indicates that several human UDP-glucuronosyltransferase (UGT) enzymes catalyze both glucuronidation and glucosidation reactions. The Sf9 cell line, derived from Spodoptera frugiperda, is used as a cell substrate for biological products, and no viruses have been reported in this cell line after extensive testing. Sf9 cells, a clonal isolate of Spodoptera frugiperda Sf21 cells (IPLB-Sf21-AE), are commonly used in insect cell culture for recombinant protein production using baculovirus.They were originally established from ovarian tissue. PubMed: 8702736. Sf9 cells are derived from pupal ovarian tissue of Spodoptera frugiperda, the Fall Armyworm. Total cell DNA was extracted from Sf9 cells using the Qiagen Gentra Puregene cell kit (Qiagen, Gaithersburg, MD). We report the presence and characterization of a soluble adenylyl cyclase (sAC) distinct from a membrane-bound form of adenylyl cyclase (mAC) that is also present in Sf9 cells. The Sf9 cell line is known to produce low-level reverse transcriptase (RT) activity (1, 2), which might be associated with particles.
