Nucleic acid labeling compounds containing heterocyclic derivatives are disclosed. The heterocyclic derivative containing compounds are synthesized by condensing a heterocyclic derivative with a cyclic group (e.g. a ribofuranose derivative). The labeling compounds are suitable for enzymatic attachment...http://www.google.es/patents/US20040210045?utm_source=gb-gplus-sharePatente US20040210045 - Nucleic acid labeling compounds
