MODELING AND EXPERIMENTAL VALIDATION OF DNA MOTION DURINGELECTROPHORESIS

摘要

This paper describes the protocol and presents the results for DNA motion experiments using fabricated macroscale gel elec-trophoresis devices. Gel electrophoresis is a process used to separate/move DNA, RNA or protein molecules using an electric field through a gel matrix (electrolytic solution). In electrolytic solutions, the current conduction is due to a transport of ions (anions and cations). A better understanding of electrophoretic fundamentals allows for modeling the motion of DNA during electrophoresis. The model is validated through comparison with the experimental results. The model and experimental validation will be used to improve the process of cellular nanoinjection of DNA, currently in development in our lab.
