A method of detecting a nucleic acid (e.g., DNA, RNA) that contains at least one preselected base (e.g., adenine, guanine, 6-mercaptoguanine, 8-oxo-guanine, and 8-oxo-adenine) comprises (a) reacting the nucleic acid with a transition metal complex capable of oxidizing the preselected base in an oxidation-reduction reaction; (b) detecting the oxidation-reduction reaction; and (c) determining the presence or absence of the nucleic acid from the detected oxidation-reduction reaction at the preselected base. The method may be used in a variety of applications, including DNA sequencing, diagnostic assays, and quantitative analysis.
一种检测含有至少一种预选碱基(如腺嘌呤、鸟嘌呤、6-巯基鸟嘌呤、8-氧代鸟嘌呤和 8-氧代腺嘌呤)的核酸(如 DNA、RNA)的方法包括:(a) 使核酸与过渡金属络合物反应、腺嘌呤、鸟嘌呤、6-巯基鸟嘌呤、8-氧代鸟嘌呤和 8-氧代腺嘌呤)的核酸的检测方法包括:(a) 使核酸与能在氧化还原反应中氧化预选碱基的过渡金属复合物反应;(b) 检测氧化还原反应;(c) 根据检测到的预选碱基的氧化还原反应确定核酸的存在与否。该方法可用于多种应用,包括 DNA 测序、诊断检测和定量分析。
