A method for conjugating a nucleic acid with a molecule is provided. The method includes steps of (a) reacting the nucleic acid having a 5′-monophosphate with an activating agent in a first buffer to form a solution; (b) mixing an alcohol with the solution formed in the step (a) to obtain an intermediate; and (c) dissolving the intermediate in a second buffer containing an ethylenediaminetetraacetic acid (EDTA) and adding a nucleophile thereinto to react the intermediate with the nucleophile.
提供了一种将核酸与分子结合的方法。该方法包括以下步骤:(a) 将具有5'-
磷酸单酯的核酸与活化剂在第一个缓冲液中反应以形成溶液;(b) 将醇与步骤(a)中形成的溶液混合以获得中间体;(c) 将中间体溶解在含有
乙二胺四乙酸(
EDTA)的第二缓冲液中,并向其中加入亲核试剂以使中间体与亲核试剂发生反应。
