The present invention relates to a method of functionalization of at least one ribonucleic acid (RNA) molecule, contained in a liquid sample, which includes the following steps: a) providing at least: one binding molecule consisting of an aza-isatoic anhydride or a derivative thereof, one group of interest, and one linkage joining the binding molecule to the group of interest, b) reacting the anhydride function of the binding molecule with at least one hydroxyl group carried: in position 2′ of the ribose of one of the RNA nucleotides, and/or in position(s) 2′ and/or 3′ of the ribose of the nucleotide at the terminal 3′ end of the RNA, and obtaining an aza-anthranilate that joins, by means of the linkage, the RNA to the group of interest.
本发明涉及一种对液体样品中至少一个核糖核酸(RNA)分子进行功能化的方法,包括以下步骤:a)提供至少:一个由氮杂异异硫酸酐或其衍生物组成的结合分子,一个感兴趣的基团,以及将结合分子与感兴趣的基团连接的一个连接部分,b)将结合分子的酐功能与至少一个羟基反应:其中该羟基携带在RNA核苷酸的核糖的2′位,和/或在RNA末端的核糖的2′和/或3′位,从而获得一种氮杂蒽酸盐,通过连接部分将RNA与感兴趣的基团连接起来。
