Homogeneous immunoassay method utilizing 5-300 mM magnesium

摘要

In a method for immunoassay of a trace component in a sample derived from a living body on the basis of a change of turbidity or scattered light intensity caused by antigen-antibody reaction, when the antigen- antibody reaction is carried out in the presence of magnesium ions previously added, an analyte can be measured rapidly and easily with high precision and reproducibility.
