Magnetic bead-based migration method and apparatus for the method

摘要

This invention relates to a method to make biopolymers such as proteins or nucleic acids migrate by applying a spatially distributed magnetic field to a solution containing biopolymers marked with magnetic beads. In this case, marking the biopolymers to be fractionated with magnetic beads of different sizes or materials causes different migration speeds and thus causes different positions of the biopolymers after migration. Molecules to be fractionated can be separated in such a manner as mentioned above.
