Agarose gel electrophoresis remains the most widely used technique for separating nucleic acid fragments because it is a simple technique that is nontoxic and offers a broad separation range. The size of the gel pores can be controlled by simply adjusting the agarose concentration to prepare gels appropriate for the separation of a wide range of different-size nucleic acid molecules. The migration of nucleic acids in agarose gels is also affected by the choice of running buffer and the applied voltage. (Learn more: Nucleic acid electrophoresis education.)
We offer convenient reagents for agarose gel electrophoresis including hassle-free precast Invitrogen E-Gel agarose gels, safe and sensitive DNA gel stains, DNA ladders, and UltraPure reagents to cast agarose gels yourself.
