Cisplatin belongs to the most widely used cytostatic drugs. The determination of the presence of the DNA-cisplatin adducts may not only signal the guanine-rich regions but also monitor the interaction reaction between DNA and the drug in terms of speed of interaction. In this work, the combined advantages of magnetic particles-based isolation/purification with fluorescent properties of quantum dots (QDs) and antibodies targeted on specific recognition of DNA-cisplatin adducts are demonstrated. The formation of a complex between magnetic particles with surface modified by anti-dsDNA antibody, cisplatin-modified DNA and QDs labelled anti-cisplatin-modified DNA antibody was suggested and optimized.
顺铂是使用最广泛的细胞毒性药物之一。DNA-顺铂加合物的存在测定不仅可以标记富含鸟嘌呤的区域,还可以从相互作用速度方面监测DNA与药物之间的相互作用反应。在这项工作中,展示了基于磁性颗粒的分离/纯化与量子点(QDs)的荧光特性以及靶向特异性识别DNA-顺铂加合物的抗体的综合优势。提出并优化了由抗双链DNA抗体修饰表面的磁性颗粒、顺铂修饰的DNA和标记有抗顺铂修饰DNA抗体的量子点之间形成复合物的过程。
