Abstract:Immunoassays are demonstrated to be simple, rapid, and cost effective. For the past decades, more and more techniques are being developed which combine the advantages of approaches in highly powerful analytical tools. The convenience and speed of the test have been achieved by a novel concept of colloidal gold based immunochromatographic assay, which depends on the transport of a color labeled reactant to its binding partner immobilized on the surfaces of the membrane. This new technique has been proved to be a well established and appropriate technique for a variety of point of care and field use applications, which was widely used as a convenient test for human being and terrestrial animal diseases in nowadays. In this paper, progress on the study of this new technique has been summarized in detail, which focuses on its principle, application and development. Based on these, its practicability in aquatic animal is also introduced. It would provide a new point of view on the innovation of simple and fast detection of disease in aquaculture.
