 | | The Biotin-Avidin System has proven to be particularly useful in the detection and localization of antigens, glycoconjugates, and nucleic acids by employing biotinylated antibodies, lectins, or nucleic acid probes. |
 | | Although each technique has its merit, it is now widely appreciated that the Biotin-Avidin System provides the highest sensitivity in fluorescence and enzyme-based detection, versatility that allows easy interchange or introduction of multiple markers, and the ability to localize or detect antigens which are difficult or impossible to see or measure with other systems. |
 | | By using either separate enzyme systems, two different substrates for the same, or assorted fluorochrome conjugates, more than one antigen can be localized in the same tissue section. |
