There are disclosed a method for assaying antigens or antibodies in the reaction medium, characterized in that a sample containing antigens or antibodies to be assayed is treated with a polyanion which is soluble in the reaction medium and thus treated sample is used for the antigen-antibody reaction; and a reagent for assaying an antigen-antibody reaction, which contains a polyanion and a reaction medium.

Method for assaying antigen-antibody reactions and reagent thereof

A method of the quantitative measurement of antigens and antibodies by reacting an antigen or antibody or a mixture thereof with the corresponding antibody and/or antigen which has been supported on insoluble carrier particles, irradiating the resulting reaction mixture with light of a specific wavelength to measure the intensity of light scattered by the reaction mixture.

Method of measurement of antigens and antibodies

A method of the quantitative measurement of antigens and antibodies by reacting antibody- or antigen-sensitized insoluble carrier particles with a corresponding antigen or antibody or a mixture thereof in a sample, irradiating the reaction mixture with light of a specific wavelength to measure the transmitted light at two or more points of time as the reaction proceeds, and then evaluating an increase in absorbance or percent absorption of the reaction mixture for a given period of time, and an apparatus for use therein.

Method and apparatus for the measurement of antigens and antibodies

A method of the quantitative measurement of antigens and antibodies by reacting antibody- or antigen-sensitized insoluble carrier particles with a corresponding antigen or antibody or a mixture thereof in a sample and irradiating the reaction mixture with light of a specific wavelength to measure the absorbance or percent absorption of the reaction mixture, and an apparatus for use therein.

A method of the quantitative measurement of antigens and antibodies by reacting antibody-or antigen-sensitized insoluble carrier particles with a corresponding antigen or antibody or a mixture thereof in a sample and irradiating the reaction mixture with light which contains rays of polychromatic light having a particular wavelength region in the range of 0.6 to 2.4 microns to measure the absorbance or percent absorption of the reaction mixture, and an apparatus for use therein.
