Serological response

Serological reactions refer to the binding reaction of the corresponding antigen and antibody in vitro. Since antibodies are mainly present in serum, serums containing antibodies are generally used as experimental materials when performing such reactions. Therefore, in vitro antigen and antibody reactions are called serological reactions. This type of reaction is based on the principle of high specificity of antigens and antibodies, that is, the known one is used to detect the presence of the other. Both qualitative and quantitative. Known antibodies can be used to detect unknown antigens, such as identifying pathogenic microorganisms; known antigens can be used to detect unknown antibodies, such as to assist in the diagnosis of a disease.
