Time-Resolved Fluoroimmunoassay

  • Erkki Soini

Abstract

The number of published fluoroimmunoassay (FIA) methods and their applications is increasing continuously and FIA has established its position as a reliable analytical method and a nonisotopic alternative to RIA (Hemmilä, 1985). It has been anticipated that RIA methods will be gradually replaced by nonisotopic methods, first by enzyraic methods and then by FIA. Indeed, EIA methods are widely applied, especially in the areas of serology, microbiology, and virology. Until now, FIA methods have had only limited applications — for example in drug monitoring and serologic assays. To be able to replace the traditional RIA methods and the already well-established EIA methods, higher sensitivity, better precision, and more widely applicable performance characteristics are required. The assay principle and the instrument should be suitable for a very wide range of analytes (from small haptens to large microbes), which may be present in either high or low concentrations (from millimolar to picomolar).
