摘要:
The present invention relates to the molecular biology and virology of the hepatitis C virus (HCV). An object of the present invention is a method to reproduce in vitro the RNA-dependent RNA polymerase activity of HCV that makes use of sequences contained in the HCV NS5B protein.
摘要:
This is a method for reproducing in vitro the RNA-dependent RNA polymerase activity associated with hepatitis C virus. The method is characterized in that sequences contained in NS5B are used in the reaction mixture. The terminal nucleotidyl transferase activity, a further property of the NS5B protein, can also be reproduced using this method. The method takes advantage of the fact that the NS5B protein, either purified to apparent homogeneity or present in extracts of overproducing organisms, can catalyze the addition of ribonucleotides to the 3′-termini of exogenous or endogenous RNA molecules. The invention also relates to a composition of matter that comprises sequences contained in NS5B, and to the use of these compositions for the set up of an enzymatic test capable of selecting, for therapeutic purposes, compounds that inhibit the enzymatic activity associated with NS5B.
摘要:
The construction of a chimeric Pestivirus by the identification of selected regions in the 3′NTR of the viral RNA genome is described where additional RNA sequences can be stably inserted. These sequence insertions in the viral RNA genome were stable in replication and capable of forming infectious, RNase resistant virus particles. This chimeric Pestivirus with a 3′NTR insertion can be utilized as a quality control material in analytical assays for RNA targets, including external, internal controls, quantitative standards in PCR and NAT nucleic acid assays.

The invention relates to the field of nucleic acid amplification, particularly to quality control materials for use in viral RNA assays. It specifically relates to the construction of a recombinant Pestivirus by the identification of a region in the 3′NTR of the viral RNA genome where additional sequence elements can be stably inserted. Chimeric Pestivirus with sequence insertions in the 3′ nontranslated region (3′NTR) of the viral RNA genome were stable in replication and capable of forming infectious, RNase resistant virus particles. This chimeric Pestivirus with a 3′NTR insertion can be utilized as a quality control material in analytical assays for RNA targets, including external, internal controls, quantitative standards in PCR and NAT nucleic acid assays.
