(5) Immunoassay (IA)
1) Radioimmunoassay (radioimmunoassay, RIA)
RIA combines the sensitivity of radioactivity with the specificity of immunity, which is simple, accurate, sensitive and reliable
2) Enzyme linked immunosorbent assays (ELISA)
ELISA uses the specific reaction of antigen and antibody to connect the test substance and enzyme, and adsorb the known antigen or antibody on the surface of the solid phase carrier, so that the antigen-antibody reaction is carried out on the surface of the solid phase carrier, and the liquid phase is washed by the washing method.
