  • Method for analysis of hepatitis B virus s antigen
    Patent number: 9052320
    Abstract: An object of the present invention is to enable to accurately quantify HBs antigen in the samples for which measured values are low or false-negative results by the conventional assaying method of HBs antigen. In the method of assaying HBs antigen according to the present invention, at least one inner capture probe that binds to a first inner region peptide consisting of 26th to 80th amino acid residues of HBs antigen and at least one outer capture probe that binds to a second outer region peptide consisting of 98th to 156th amino acid residues of HBs antigen are used as capture probes; and at least one inner detection probe which binds to the first inner region and at least one outer detection probe which binds to the second outer region are used as detection probes.
