Versatile sample input ranging from 0.5 mL to 2 mL No time-consuming ultracentrifugation, filtration nor special syringes required No precipitation reagents or overnight incubation required No protease treatment required Purify pure exosomes that are free from RNA-binding proteins Analyze purified exosomes using NanoSight® or Electron Microscopy for assessing the approximate exosome size range and concentration Process fresh saliva or saliva collected with Norgen's Saliva Exosome Collection and Preservation Kit (Cat 65400) . Isolate high quality RNA from purified exosomes using Norgen's Exosome RNA Purification Kit (Cat. 58000) Purification is based on Norgen’s proprietary resin Norgen’s Saliva Exosome Purification Kit allows for the purification of saliva exosomes from 500 μL to 2 mL of fresh saliva samples or saliva samples collected using Norgen's Saliva Exosome Collection and Preservation Kit (Cat 65400) . This kit also allows for the purification of intact extracellular vesicles (EVs) from different saliva sample volumes, and these EVs are ready for any downstream application. The purification is based on Norgen’s proprietary resin. These kits provide a clear advantage over other available kits in that they do not require any special instrumentation, precipitation reagents or any protease treatments. More importantly, the purified exosomes will not be contaminated with any other RNA-bound proteins that may contaminate your exosomal RNA, which is essential if studying exosomal RNA gene expression.
