pBG256 Recombinant Sindbis Virus Replicon Packaging Plasmid

Recombinant packaging plasmid pBG256 lacking the virla nsP1-nsP4 replication genes and can be used to combine plasmids with pBG60, pBG68 and pBG78.

The Sindbis virus genome lacking the viral nsP1-nsP4 replication genes and possessing the viral structural protein genes under the control of the native viral subgenomic promoter was inserted into the pcDNA3.1 Zeo+ expression vector such that the transcription start site of the CMV promoter overlaps with the first viral nucleotide of the viral genome. A Hepatitis D virus (HDV) ribozyme was added to the 3' end of the viral genomic 35 base polyA sequence. Transfection this construct into mammalian cells produces a Sindbis virus genome that cannot express the viral structural proteins unless the viral nsP1-nsP4 replication proteins are provided in trans by a co-transfected replicon plasmid (pBG60, pBG68, pBG78). This construct was found to be superior to the pBG44 packaging construct described in Geiss et al., 2007 in production of virus-like particles. Equimolar amounts of replicon and packaging plasmids should be transfected into cells for optimal results.
