    • A method of purifying full length synthetic target oligonucleotides from a mixture of oligonucleotides, particularly from a mixture containing truncated or failed sequences. The method involves attaching a short nucleotide sequence complementary to the 5' end of a target oligonucleotide to a solid support. The complementarity between the most 5' nucleotides of the target oligonucleotide and the bound oligonucleotide results in hybridization which serves to retain the target oligonucleotide. Truncated or failed sequences lacking 5' sequences complementary to the attached oligonucleotide, fail to hybridize and therefore are not retained. The method makes it possible to purify gram quantities of synthetic deoxyribonucleic acids or ribonucleic acids and sequences which have modifications, such as on the phosphate backbone. The support-bound nucleotide sequences are stable under conditions of purification and therefore can be reused.
    • 从寡核苷酸的混合物,特别是含有截短或失败序列的混合物中纯化全长合成靶寡核苷酸的方法。 该方法包括将与靶寡核苷酸的5'末端互补的短核苷酸序列连接到固体支持物上。 靶寡核苷酸的最多5'核苷酸与结合的寡核苷酸之间的互补性导致用于保留靶寡核苷酸的杂交。 缺少与所连接的寡核苷酸互补的5'序列的截短或失败序列不能杂交,因此不保留。 该方法使得可以纯化克数量的合成脱氧核糖核酸或核糖核酸和具有修饰的序列,例如在磷酸酯骨架上。 支持结合的核苷酸序列在纯化条件下是稳定的,因此可以重复使用。
