The EX01 Exo-spin™ kit has been developed to process up to 50 ml of cell culture medium, saliva, urine, cerebrospinal fluid (CSF), human breast milk and other low-protein biological fluids. The kit includes Exo-spin™ buffer as well as SEC columns. The Exo-spin™ buffer is a polymer-based precipitation buffer and will be used for the first step. For the second step, pre-packed and equilibrated ready-to-use SEC columns are included.
