The present invention provides a new labeling reagent for preparing modified oligonucleotides and processes for their production wherein these oligonucleotides contain at least once the structure P═N—SO2-benzole-L-M-X, characterized in that L is either —(CH2)n- or polyethylene glycol, M is selected from a group consisting of —NH—, —O—, —S—, and —COO—, and X is either a protecting group or a detectable unit. L is preferably either —(CH2)n- or polyethylene glycol.
本发明提供了一种新的标记试剂,用于制备修饰寡核苷酸,并提供其生产工艺。其中这些寡核苷酸至少包含一次P═N—SO2-benzole-L-M-X结构,其中L为—(
CH2)n-或聚
乙二醇,M从—NH—,—O—,—S—和—COO—组成的一组中选择,X为保护基或可检测单元。L最好是—( )n-或聚
乙二醇。
