RNA interference (RNAi) is the best way to effectively knock down gene expression and study protein function in a wide range of cell types. The use of vectors to perform RNAi experiments greatly expands experimental possibilities beyond traditional small/short interfering RNAs (siRNAs). Having evolved to proficiently deliver nucleic acids to cells, viruses offer a means to reach hard-to-transfect cell types for protein overexpression or knockdown.
