Exo-spin standard, 8 columns, 60 ml buffer

Exo-spin™ technology combines precipitation and size exclusion chromatography (SEC), providing flexibility and performance. Using only precipitation for exosome isolation co-purifies large amounts of non-exosomal proteins and other material, as well as carried-over precipitant. SEC is reliable for exosome isolation, but a step is needed for low-exosome content starting material (such as cell culture media) to concentrate the sample prior to SEC isolation. For most applications, precipitation is the simplest way to achieve this concentration. Small samples can be purified directly. For larger samples we provide a simple, two-step protocol that allows consistent and reliable purification of samples in under 2 hours. Iterative loading can also be used to increase loading sample volume.
