Vector-based siRNA has stronger in vivo and in vitro inhibitory effects than synthetic siRNA and can work with tissue or cell-specific promoters. As regarding stable cell lines can be developed, vector-based siRNA allows researchers to observe the longterm knock-down effects of their target genes. The inducible expression feature adds another layer of flexibility. Hiragene vector-based siRNA technology is an adaptation of Hiragene gene synthesis technology to the rise of RNA interference (RNAi) as a powerful tool for gene function analysis and drug target validation. In Hiragene we can assist you to identify the most effective siRNA sequences with strong gene silencing effect, and clone into any cloning vectors you desire.
