The protocol describes a method for introducing controllable genetic diversity in the hepatitis C virus genome by combining full-length mutant RNA synthesis using error-prone PCR and reverse genetics. The method provides a model for phenotype selection and can be used for 10 kb long positive-sense RNA virus genomes.

Nuclear magnetic resonance (NMR) spectroscopy is used to identify dysregulation in the metabolites in patients with various diseases. This technique allows the quantification of the deranged metabolites, unraveling the pathophysiological insights. Here, we describe the step-by-step procedure of the NMR-based approach for the metabolic characterization of the patients.
