Induction of cytokines is a significant problem associated with nucleic acid delivery systems. This induction is the result of specific nucleic acid sequence as well as the nature of the delivery system.  InVivoPlex™ –TUMOR shows very low level of cytokine induction when delivering an siRNA oligonucleotide, and most importantly also plasmid DNA containing CpG motifs.  In addition, InVivoPlex™ –TUMOR has a very good safety profile, including low liver toxicity unlike other in vivo delivery system reagents for nucleic acids.
