Application progress of time-resolved fluorescence in immunoassay / 公共卫生与预防医学

ABSTRACT

Time resolved fluoroimmunoassay (TRFIA) is an immunoassay technology developed on the basis of the unique fluorescence properties of rare earth elements. TRFIA combines the advantages of radioimmunoassay, enzyme-linked immunoassay and common fluorescence immunoassay. It has high sensitivity, strong specificity, good stability, wider measurement range, long fluorescence life, simple operation and non-radiation, and shows a good prospect in the field of immunoassay. In this paper, several common TRFIA materials are discussed based on the latest research progress of time-resolved fluorescence in immunoassay. The application of TRFIA in immunodiagnosis, food detection, environmental monitoring and so on is elaborated, and its development direction and application are prospected.
