ECLIA
Electro chemiluminescence immunoassay (ECLIA) Antibody-bound beads are reacted with antigens that are secondarily reacted with antibodies labeled with rutheniumpyridine complexes, which promotes the electrochemical reaction. The emission intensity of ruthenium-pyridine complexes is measured.

RIA solid phase method
Immunoradiometric assay (IRMA) IRMA is one of the techniques of RIA. Antibodies linked to the solid phase are reacted with antigens that are secondarily reacted with antibodies labeled with radioactive isotope (RI). This is also called as the sandwich technique, because the solid-phase linked antibodies and the RI-labeled antibodies bind to the antigens, respectively, forming an antigen sandwich.

Radio immunoassay (RIA) A target antigen is labeled with radioactive isotope (RI) and bound to its specific antibodies which is then competitively reacted with an antigen in a specimen. After the antigen-antibody reaction, the bound labeled antigens (bound) are separated from the unbound ones (free), and the antigen concentration is determined based on the proportion of radioactivity. To separate the bound and free antigens (B/F separation), the following methods are used. Solid-phase method:Antibodies are linked to the solid phase. Double antibody method: Antigen-antibody complexes are bound to the second antibody and precipitated. Ammonium sulfate precipitation method: Antigen-antibody complexes are precipitated by ammonium sulfate. PEG method: Antigenantibody complexes are precipitated by a precipitation reagent.

Colorimetry After converting an analyte to a coloring substance, a visible wavelength is irradiated. The absorbance is measured, and color of the analyte is compared with that of the standard solution.
