Model RNA Standards
Stable Isotope-Labeled r14-mer RNA Standard
Silantes offers high quality stable isotope-labeled ribo oligonucleotides for monitoring the performance of NMR-spectrometers and for testing new pulse-sequences. Read More
The Silantes 14-mer oligo-ribonucleotide NMR standard is folded into a very stable hairpin. The structure of a very similar sequence was solved by NMR as described by Varani et al. (Varani, G. et al., Biochemistry, Vol. 30, No. 13, 1991, pp 3280 – 89).
Original sequence (Varani, G. et al.): 5′ – pppGGA CUU CGG UCC-3′
Silantes sequence: 5′ – pppGGC ACU UCG GUG CC – 3′
The original sequence was completed by an additional GC base pair.
Isotope Enrichment > 98 %, Chemical Purity > 95 %
The isotope enrichment of the NMR standards is verified by NMR analysis. The chemical purity of the NMR standards is verified by ion-exchange chromatography for RNA standards.
Ready-to-use
Our NMR standards are available in both solid powder form and as concentrated solution (550 µL) prepackaged in a ready-to-use 5 mm NMR tube.
