The purpose of this research is to develop a multi-type (96 hole)quartz-crystal microbalance (QCM In this paper, we introduce a 27-MHz quartz-crystal microbalance (QCM) as a new tool to detect DNA-protein/peptide interactions in an aqueous buffer solution. From the time course of the frequency decrease (mass increase), the binding amount (Δm), association constant (Ka), binding and dissociation rate constant (k1 and k1) can be obtained. When dsDNA was immobilized on a QCM, binding kinetics of antibiotics, a Zinc-finger type peptide, a restriction enzyme, and a polymerase to DNA strands could be obtained in aqueous buffer solution. The 27-MHz QCM is highly sensitive and quantitative enough to detect various molecular interactions on DNA double strands.

本研究的目的是研制一种多类型(96孔)的石英晶体微天平(QCM)。本文介绍了一种27 MHz的石英晶体微天平(QCM)，它是一种检测水溶液中DNA-蛋白质/肽相互作用的新工具。从频率降低(质量增加)的时间过程可以得到结合量(Δm)、缔合常数(Ka)、结合和解离速率常数(K1和K1)。当dsDNA固定在QCM上时，在水缓冲液中可以获得抗生素、锌指状肽、限制性内切酶和聚合酶与DNA链的结合动力学。27 MHz的QCM具有高度的灵敏度和定量能力，足以检测DNA双链上的各种分子相互作用。
