Cyanogen bromide was found to induce a smooth and highly efficient condensation of oligonucleotide blocks within DNA duplexes. This template-directed reaction proceeds in the aqueous solution at 0 degree C for 1-2 min. Cyanogen bromide catalyzes the formation not only of phosphodiester, but also of unnatural phosphoramide and pyrophosphate interoligomer bonds.
发现溴化氰能诱导DNA双链内寡核苷酸片段进行顺利且高效的缩合。这种模板导向反应在0摄氏度的水溶液中进行1 - 2分钟。溴化氰不仅催化磷酸二酯键的形成,还催化非天然的磷酰胺键和焦磷酸酯键在寡聚物间的形成。
