Abstract
The present invention relates to a sandwich immunoassay for rapidly and readily measuring N-peptide using two kinds of monoclonal antibodies recognizing different portions of the N-peptide. The method for measuring N-peptide or a precursor thereof includes the steps of: incubating a mixture containing a sample and a first monoclonal antibody recognizing a portion of N-peptide; adding a labelled second monoclonal antibody recognizing a portion of N-peptide to the mixture, followed by further incubation; and detecting the resulting antigen-antibody complex in the mixture. Alternatively, the method includes the steps of: incubating a mixture containing a sample, a first monoclonal antibody recognizing a portion of N-peptide, and a labelled second monoclonal antibody recognizing another portion of N-peptide; and detecting the resulting antigen-antibody complex.
