Chromatography Resins for Desalting, Buffer Exchange, and Oligonucleotide Purificationn
Chromatography Resin
emp Biotech offers a versatile selection of dry and pre-hydrated chromatography resins designed for the desalting, buffer exchange, and purification of oligonucleotides and nucleic acids. Based on our proprietary Zetadex™ matrix, these gravity-flow-compatible resins deliver reproducible performance across research, diagnostics, and production workflows. Available in a range of bead sizes and buffer systems, each resin ensures high sample recovery, low nonspecific binding, and reliable separation of biomolecules from salts and small molecules.
