    Area of Science:

    • Biochemistry
    • Immunology
    • Analytical Chemistry

    Background:

    • Radioimmunoassay (RIA) and Enzyme Immunoassay (EIA) are established protein detection methods.
    • Fluoroimmunoassay (FIA) presents a novel approach combining the strengths of RIA and EIA.
    • Advancements in fluorescent labels offer new possibilities for sensitive detection.

    Purpose of the Study:

    • To review the principles and applications of protein fluoroimmunoassay (FIA).
    • To discuss antibody production and different FIA formats (homogeneous, heterogeneous, time-resolved).
    • To evaluate the potential of various fluorescent labels and FIA instrumentation.

    Main Methods:

    • Description of antibody production techniques.
    • Explanation of homogeneous, heterogeneous, and time-resolved FIA principles.
    • Analysis of 28 fluorescent labels, including aminoquinolone, cyanocoumarines, chlorophylls, phycobiliproteins, and metallorganic compounds.

    Main Results:

    • FIA combines advantages of RIA and EIA for protein quantification.
    • Identified 28 prospective fluorescent labels for enhanced assay sensitivity.
    • Reviewed FIA kits and fluorimeter specifications for practical application.

    Conclusions:

    • FIA is a promising technique for quantitative protein analysis in biological samples.
    • Further development in fluorescent labels and instrumentation will expand FIA applications.
    • FIA holds significant potential for future medical and biological research.
