Conjugate for measuring multivalent antigen, immunochromatography and measurement methods immunochromatographic test strip for measuring multivalent antigen of using this

摘要

In the immunochromatography measurement method and measured the multivalent antigen, used as a labeled form of gold colloid, the present invention aims to provide an immunochromatographic test strip for measuring multivalent antigen with a wide measurement range. A conjugate for measuring multivalent antigen obtained from a mixture of the gold colloidal solution with a solution of monoclonal antibody against a multivalent antigen to be measured, the antibody concentration of the mixed solution is, to colloidal gold of the antibody The use of the conjugate for measuring multivalent antigen which is characterized in that the antibody concentration of 1/4 to 1/2 of the maximum binding antibody concentration, and was able to make it possible to measure a wider range than the conventional .
