Available separately or as part of the BacPAK™ Baculovirus Expression System (Cat. No. 631402). pBacPAK9 is a transfer vector designed for high-level expression of a cloned gene driven by the strong AcMNPV polyhedrin promoter. Flanking AcMNPV sequences allow recombination with viral DNA to transfer the expression cassette to the polyhedrin locus of the viral DNA. The polyhedrin coding sequences have been replaced by a multiple cloning site with 18 unique sites which facilitate the insertion of foreign genes in the correct orientation for expression. The Pac I site at the end of the MCS region provides translational stop codons in all three reading frames for expression of truncated proteins. pBacPAK9 has a pUC origin of replication, an M13 origin for single-stranded DNA production, and an ampicillin resistance gene for selection in E. coli.
