使用一种简单、高选择性的生物传感器进行ATP定量分析。在这里,我们引入两个发夹探针作为矩阵。当Exo III消化它们的双链体时,被阻断的G-四链体释放。然后N-甲基中卟啉IX(NMM)与G-四链体结合产生强荧光。但是当加入ATP时,它触发了T4 DNA连接酶将两个发夹连接起来。结果,Exo III不能水解发夹,导致低信号输出。该方法对ATP的检测限为3.75 nM,线性范围为5-300 nM。该方法具有良好的选择性和特异性,无需繁琐的处理和标记过程。
A facile, highly selective biosensor was used for ATP quantitative analysis. Here we introduce two hairpin probes as the matrix. While Exo III digested their duplexes, the blocked G-quadruplex released. Then N-methyl mesoporphyrin IX (NMM) integrated with G-quadruplex to produce strong fluorescence. But when ATP was added, it triggered the T4 DNA ligase to link the two hairpins. As a result, Exo III could not hydrolyze the hairpins leading to a low signal out. With this method, the detection limit reached 3.75 nM, and linear range 5–300 nM for ATP. This method has good selectivity and specificity without a tedious treatment and label process.
