A novel hepatitis C virus NS5B polymerase assay of de novo initiated RNA synthesis directed from a heteropolymeric RNA template.
Methods in molecular biology (Clifton, N.J.)(2013)
摘要
The hepatitis C virus (HCV) NS5B RNA-dependent RNA polymerase is essential for viral replication and a clinically validated antiviral target. Discovery of HCV polymerase inhibitors is greatly facilitated by the availability of a suitable biochemical assay using purified NS5B. We describe here a novel NS5B polymerase assay of de novo initiated RNA synthesis directed from a synthetic heteropolymeric RNA template modified with dideoxycytidine at its 3'-end. This assay has been successfully used for screening and characterization of both initiation and elongation inhibitors of the HCV NS5B polymerase.
