The invention consists of compounds and methods for the synthesis of oligonucleotides which contain one or more free aliphatic amino groups attached to the sugar moieties of the nucleoside subunits. The synthetic method is versatile and general, permitting amino groups to be selectively placed at any position on oligonucleotides of any composition or length which is attainable by current DNA synthetic methods. Fluorescent dyes or other detectable moieties may be covalently attached to the amino groups to yield the corresponding modified oligonucleotide.
该发明包括化合物和合成寡核苷酸的方法,其中这些寡核苷酸含有一个或多个连接到核苷苷基亚甲基氨基的自由脂肪族氨基。这种合成方法是多功能且通用的,允许氨基被选择性地放置在由当前DNA合成方法可实现的任何组成或长度的寡核苷酸的任何位置。荧光染料或其他可检测的基团可以共价连接到氨基上,从而得到相应的修饰寡核苷酸。
