Abstract
In this reaction, the enzyme terminal transferase is used to introduce a short tail of fluorescein nucleotides to the 3′-end of an oligonucleotide (1) followed by horseradish peroxidase-catalyzed enhanced chemiluminescent detection of the labeled hybrids. This approach is used in the ECL 3′-oligolabeling and detection system (Amersham International, Amersham, UK) for hybridizations on membranes. In general, oligonucleotide probes are used for lower sensitivity applications, and the combination of fluorescein-labeling and enhanced chemiluminescent detection allows as little as 20 × 10−18 mol of homologous target to be detected within a 1-h exposure.
