It presents a simple method for the analysis of nucleic acids in the lab. Biochemistry Real-time Tracking of DNA Fragment Separation by Smartphone Chunxian Tao1, Bo Yang1, Zhenqing Li1, Dawei Zhang1, Yoshinori Yamaguchi1,2,3 1Shanghai Key Lab of Modern Optical System, University of Shanghai for Science and Technology, 2Department of Applied Physics, Graduate School of Engineering, Osaka University, 3East China University of Science and Technology, Department of Physics Faculty of Science Traditional slab gel electrophoresis (SGE) experiments require a complicated apparatus and high chemical consumption. This work presents a protocol that describes a low-cost method to separate DNA fragments within a short timeframe.
