| Biosensors can be used in conjunction with enzyme-linked immunosorbent assays (ELISA). ELISA is used to detect and amplify an antigen-antibody reaction; the amount of enzyme-linked antigen bound to the immobilized antibody being determined by the relative concentration of the free and conjugated antigen and quantified by the rate of enzymic reaction. Enzymes with high turnover numbers are used in order to achieve rapid response. The sensitivity of such assays may be further enhanced by utilizing enzyme-catalyzed reactions which give intrinsically greater response; for instance, those giving rise to highly colored, fluorescent or bioluminescent products. Assay kits using this technique are now available for a vast range of analyses. | ||
