A method for joining oligonucleotides. The method includes joining together one or more oligonucleotides by reacting an alkyne group lined to an oligonucleotide with an azide group linked to an oligonucleotide to form a triazole linkage. The alkyne group is a strained alkyne group. The method can include ligating together ends of one or more oligonucleotides or cross-linking strands of an oligonucleotide duplex. The methods described allow oligonucleotide strands to be ligated together without the need for a ligase enzyme.
一种连接寡核苷酸的方法。该方法包括通过将连接到寡核苷酸的炔基与连接到寡核苷酸的
叠氮基反应以形成三唑键来连接一个或多个寡核苷酸。炔基是一种受应力的炔基。该方法可以包括连接一个或多个寡核苷酸的末端或交联寡核苷酸双链的链。所描述的方法允许寡核苷酸链在无需连接酶的情况下连接在一起。
