RNA Interference

Innovative RNAi Tools

shRNA | siRNA | miRNA

RNA interference (RNAi) is a successful gene silencing process that targets specific messenger RNAs (mRNAs) and knocks down protein expression.

RNAi provides an approach to directly knock down the level of a gene transcript. This technology, in contrast to CRISPR sgRNA which knocks out a gene target at the genomic level, does not alter the genomic DNA. Also, shRNA knockdown typically occurs more rapidly than CRISPR knockout and is reversible - when the shRNA is removed, expression levels of the target gene return to normal. Finally, RNAi knockdown makes use of an endogenous pathway in mammalian systems, so only expression of the shRNA is required, unlike with CRISPR where co-expression of the Cas9 nuclease is necessary for the system to work.

BioCat supplies comprehensive and innovative RNAi tools such as shRNA (small hairpin RNA), siRNA (small interfering RNA), and miRNA (microRNA). Utilizing  superior RNAi technology can aid you in the exploration and modulation of gene expression.
