Product Description
Extracellular vesicles (EVs), a family of membrane enclosed vesicles secreted by various types of cells, are involved in cell-to-cell communication by transferring cargos, such as proteins, metabolites, and nucleic acids. A key caveat to the clinical exploitation of EVs is that traditional method of choice for EV isolation, the ultracentrifugation, requires prohibitively long time and efforts, this is even true for large scale studies and less experienced researchers who want to isolate EVs in a timely and cost-effective manner with a required yield and at a suitable scale. Therefore, a methodology that will allow the rapid isolation of EVs with high yield would greatly facilitate such applications.

One familiar method that is increasingly being applied to isolate EVs is the use of precipitants such as polyethylene glycol (PEG) combined with centrifugation to obtain pellet EVs for subsequent processing. Precipitation method has several advantages; (i) familiar to use, (ii) uses common laboratory equipment, (iii) suitable for both small and large sample volumes, (iv)high yield. However, it also has the limitations: (i) polymeric contaminants, (ii) extended processing time, (iii) complicated clean-up steps, (iv) affecting downstream analysis and quantification.
ExoPRISM^TM EV Isolation Kit for Plasma/Serum, as a novel precipitation method, is introduced to overcome those hurdles by using low-molecular-weight electrolytes instead of the PEG polymer. (i) The isolated and enriched EV sample by ExoPRISM^TM doesn't have polymeric contaminants. (ii) Due to the quick reaction of our reagents and the sample within 10 minutes, the overall processing time is significantly reduced. (iii) ExoPRISM^TM reagents can be easily removed from the enriched EVs and allows elution by the buffer solution of your choice. (iv) As a result, ExoPRISM^TM has no effect on downstream analysis or applications.The major protein contaminants like albumin and fibrinogen are effectively removed during the procedure.
ExoPRISM^TM EV Isolation Kit for Plasma & Serum

The kits include two types of reagents: Reagent P and Reagent Q, which are optimized for plasma and serum samples, respectively. The Reagent P is an EV precipitation solution and the Reagent Q is a washing solution.
