Azide C4 NHS Oligo Modification
Azide C4 NHS modified oligo is a post synthesis reaction with a reactive primary amino modified oligo. After synthesis and further purified, the azidde NHS ester is than manually attached to the oligonucleotide post-synthetically follow with step 2 purification process. This modification can be place at any position within can oligonucleotide. As a result, the alkyne group is separated from the oligo by a spacer arm of varying length, which serves to reduce steric interaction between the reactive group and the oligo. This azide functionalized oligo can be used to attach alkyne modified biomolecule through the click reaction using copper (I) iodide as a catalyst) to conjugate the azide-modified oligo to a terminal alkyne-modified oligo, peptide or other biomolecule with extremely high regioselectivity and efficiency (1,2) .

-20°C To -70°C
Oligonucleotides are stable in solution at 4°C for up to 2 weeks. Properly reconstituted material stored at -20°C should be stable for at least 6 months. Dried DNA (when kept at -20°C) in a nuclease-free environment should be stable for years.
