The non-structural protein 5 (NS5) from hepatitis G virus (HGV) is a helicase, an enzyme that unwinds nucleic acid duplexes with a distinct directional polarity.The synthetic peptide used to raise the antibody Cat. No. 250689 is selected from a sequence within the C-term region of HGV-NS5. For blocking experiments, a 10 to 100 fold molar excess to antibody is recommended.
