ABSTRACT
[reaction: see text] A facile procedure for the incorporation of N-methyl phenothiazine as the terminal nucleoside in oligodeoxynucleotides is reported. The phenothiazine nucleoside analogue is synthesized and then incorporated into DNA using an automated DNA solid-phase synthesizer. Phenothiazine-labeled oligodeoxynucleotides form stable B-form duplexes with higher melting temperatures compared to unlabeled DNA duplexes.
