Abstract: Reaction mixtures are provided having at least a first nucleotide analog and a second nucleotide analog that produce signals in response to excitation illumination. The signals produced by the analogs have peaks at the same wavelengths, but have distinct signal intensities. The distinct intensities allow for identification of the analogs in nucleic acid sequencing. In some embodiments, FRET-labeled compounds are provided. In certain embodiments, FRET-labeled nucleotide analogs are used, for example, in DNA sequencing or RNA sequencing.

Abstract: The present disclosure provides a solid phase method of making oligonucleotides via sequential coupling cycles including at least one coupling of a dinucleotide dimer subunit to a free 3?-terminal group of a growing chain. The oligonucleotides include at least two nucleoside subunits joined by a N3??P5? phosphoramidate linkage. The method may include the steps of (a) deprotecting the protected 3? amino group of a terminal nucleoside attached to a solid phase support, said deprotecting forming a free 3? amino group; (b) contacting the free 3? amino group with a 3?-protected amino-dinucleotide-5?-phosphoramidite dimer in the presence of a nucleophilic catalyst to form an internucleoside N3??P5? phosphoramidite linkage; and (c) oxidizing (e.g., sulfurizing) the linkage. The compositions produced by the subject methods may include a reduced amount of one or more (N?x) oligonucleotide products. Also provided are pharmaceutical compositions including the subject oligonucleotide compositions.
