Norgen’s Exosome Purification Kits enable fast, flexible, robust, and convenient intact exosome purification from a wide range of cell-free liquid biopsies and cell-free cell culture media. Relying on Norgen’s proprietary resin technology, the intact exosomes are purified in 30 minutes and are free from any cell-free circulating protein-bound RNA which typically contaminates exosomes and impedes effective exosomal content analyses. Norgen’s intact exosome purification methodology does not involve any troublesome and tedious ultracentrifugation, any chemical or immuno-precipitation techniques, any protease or coagulant treatments and doesn’t require any special equipment or overnight incubation. The purified intact exosomes are amenable to labelling, counting, imaging, and in vivo / in vitro functional studies, as well as exosomal analyte isolations and analyses.
