Recombinant plasmid pBG210 containing Sindbis virus (SINV) allows for fast gene of interest addition with Gateway recombination.
The entire Sindbis virus genome 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 35bp polyA sequence. A Gateway recombination cassette is present behind the 3' subgenomic promoter to allow genes of interest in pDONR plasmids to be easily inserted into the replicon. Transfection of Gateway recombined versions of construct into mammalian cells produces a self-replicating Sindbis virus genome that expresses the genes of interest that will be expressed only when the virus genome is replicated. Transfection of Gateway recombined variants of this construct into mammalian cells produces an infectious self-replicating Sindbis virus genome that can express genes of interest in vitro or in vivo.
