Expression Systems offers 293 and CHO mammalian cell lines adapted to serum-free suspension culture in ESF SFM. The availability of pre-adapted cells saves significant time and expense associated with the adaptation of cultures.
Molecular Tools
BestBac - Linearized DNA - Linearized Baculovirus DNA for Cotransfection
Expression Systems’ popular BestBac Linearized Baculovirus DNA backbone has been engineered to deliver highly efficient recombination with all polyhedron gene locus based transfer vectors. The resulting virus vector provides superior stability and purity compared to other systems. BestBac is available with a deletion or wild-type at the V-cath/chiA region and sold individually or in kits. For technicians who depend on a reliable and straightforward process to meet deadlines, minimize costs and avoid the frustration of delays, Expression Systems’ BestBac offers powerful advantages over the older and antiquated Bac-to-Bac technology.
