Abstract Background HCV is circulating as a heterogeneous group of quasispecies. It has been addressed that siRNA can inhibit HCV replication in-vitro using HCV clone and or replicon which have only one genotype. The current study was conducted to assess whether siRNA can inhibit different HCV genotypes with many quasispecies and to assess whether consensus siRNA have the same effect as regular siRNA. Methods We generated two chemically synthesized consensus siRNAs Z3 and Z5 which cover most known HCV genotype sequences and quasispecies using Ambium system. Highly positive HCV patient s serum with nine quasispecies was transfected in-vitro to Huh-7 cell line which supports HCV genotype-4 replication. siRNA Z3 Z5 were transfected according to Qiagen Porta-lipid .
