RNASep™ Semi-Prep is a high capacity RNA purification column that uses alkylated non-porous polystyrene-divinylbenzene (PS-DVB) copolymer microspheres for high performance nucleic acid separations. These versatile columns can be used with a variety of HPLC systems for RNA analysis and purification. They are also ideal for the development of effective mRNA vaccines and other novel drug candidates. See our Custom mRNA Purification Solutions for details.
