This disclosure provides electrochemically-cleavable linkers with cleavage potentials that are less than the redox potential of the solvent in which the linkers are used. In some applications, the solvent may be water or an aqueous buffer solution. The linkers may be used to link a nucleotide to a bound group. The linkers include a cleavable group which may be one of a methoxybenzyl alcohol, an ester, a propargyl thioether, or a trichloroethyl ether. The linkers may be cleaved in solvent by generating an electrode potential that is less than the redox potential of the solvent. In some implementations, an electrode array may be used to generate localized electrode potentials which selectively cleave linkers bound to the activated electrode. Uses for the linkers include attachment of blocking groups to nucleotides in enzymatic oligonucleotide synthesis.
这份披露提供了具有低于使用的溶剂的氧化还原电位的可电化学裂解连接物。在某些应用中,溶剂可能是水或水溶液缓冲液。这些连接物可用于将核苷酸连接到结合基团。连接物包括可裂解基团,可能是甲氧基苯甲醇、酯、丙炔硫醚或三氯乙基醚中的一种。通过产生低于溶剂的氧化还原电位的电极电位,可以在溶剂中裂解这些连接物。在某些实施中,可以使用电极阵列来产生局部电极电位,从而选择性地裂解与激活电极结合的连接物。这些连接物的用途包括在酶催化寡核苷酸合成中将阻断基团附着到核苷酸上。
