Exo-spin™ products provide a proven, rapid and reliable way of generating high quality purified exosomes suitable for a range of research applications. Exo-spin™ technology is based on size exclusion chromatography (SEC), which is reliable for exosome isolation. A concentration step is recommended if a starting sample has low exosome-content. This includes cell culture media, urine, saliva etc. Without this important step, a lower exosome recovery will be obtained. Exo-spin™ provides a simple protocol which allows you to purify your sample in less than 2 hours with consistent and reliable results. The EX04 Exo-spin™ product contains packed and equilibrated ready-to-use SEC columns. The EX04 Exo-spin™ kit has been developed to process up to 500 ml of cell culture medium, saliva, urine (when used in conjunction with a conncentrating (e.g. precipitation) step. 1 ml of blood samples (plasma and sera) may be added onto the column directly.
