Abstract

New fluorescent nucleosides, methoxybenzodeazaadenine ((MD)A) and methoxybenzodeazainosine ((MD)I) which can sharply distinguish between C and T bases, respectably. The hybridization of an ODN probe containing (MD)A and (MD)I with a target DNA facilitates the judgment with the fluorescence spectra of the type of pyrimidine bases located at a specific site on the target DNA. The (MD)A- and (MD)I containing ODN are very effective probes for pyrimidine SNP typing.

利用新型荧光核苷的荧光变化清晰区分互补链上的嘧啶碱基。
新的荧光核苷,甲氧基苯并二氮杂腺嘌呤((MD)A)和甲氧基苯并二氮杂苷((MD)I),分别能明显区分C和T碱基。含有(MD)A和(MD)I的ODN探针与靶DNA杂交,便于利用荧光光谱判断靶DNA上特定位点的嘧啶碱基类型。含有ODN的(MD)A-和(MD)I是非常有效的嘧啶SNP分型探针。
