method for early detection of seroconversion of an antibody against hepatitis c virus

摘要

Detecting seroconversion in an assay for detecting an antibody to hepatitis C virus in a liquid sample comprises incubating the sample with a polypeptide and detecting antibody-polypeptide binding. The polypeptide corresponds to a hepatitis C virus protein fragment containing cysteine residues and has cysteine residues that are covalently modified or replaced by other amino acids.
