This unit describes two protocols for the deprotection of 2'-O-TBS groups in oligoribonucleotides under mild conditions. Desilylation using ammonium fluoride is applicable to fully protected "RNA only" substrates and desilylation using potassium fluoride is applicable to "mixed RNA/non-RNA" substrates. Characterization of products is accomplished using LC/MS, RP HPLC and SAX HPLC.
本单元描述了在温和条件下对寡核糖核苷酸中2'-O-TBS基团进行脱保护的两种方法。使用氟化铵进行去硅烷基化适用于完全保护的“仅RNA”底物,使用氟化钾进行去硅烷基化适用于“RNA/非RNA混合”底物。产物的表征通过液相色谱/质谱、反相高效液相色谱和强阴离子交换高效液相色谱来完成。
