A method for phosphorylating a protected deoxyribooligonucleotide containing phosphotriester linkages is described. The modified phosphotriester method of chemical synthesis is further refined in terms of (i) better final deblocking conditions and (ii) new chromatography solvent systems containing acetone-water-ethyl acetate to yield pure oligomers. The effectiveness of these improvements has been demonstrated in the rapid and efficient synthesis of seventeen fragments constituting the sequence of human insulin C-chain DNA.
描述了一种对含有磷酸三酯键的受保护脱氧核糖寡核苷酸进行磷酸化的方法。化学合成的改进磷酸三酯方法在以下方面得到了进一步完善:(i)更好的最终脱保护条件,以及(ii)含有丙酮 - 水 - 乙酸乙酯的新型色谱溶剂系统,以产生纯的寡聚物。这些改进的有效性已在快速高效合成构成人胰岛素C链DNA序列的17个片段中得到证明。
