Optimised for Serum, Plasma, and Cell Culture Supernatant.
What is ExoCap™?
ExoCap™ is a kit for exosome isolation and enrichment designed and optimised for use with serum, plasma and cell culture supernatants. This kit consists of magnetic particles coupled with antibodies that recognise the exosome surface antigens (CD9, CD63, CD81, or EpCAM), treatment buffer, washing/dilution buffer, and exosome elution buffer.
ExoCap™ uses functionalized Magnosphere™ magnetic microparticles for exosome separation. These beads are coated with a JSR Life Sciences proprietary polymer and cofactors which specifically bind to exosomes.
Features and Advantages
- Simple: Simple workflow, easy-to-follow with minimum hands-on time, protocol. Direct isolation possible, no front-end precipitation or ultracentrifugation needed.
- Specific: Targets specific antigens for purification of a defined exosome population.
- Versatile: Optimised for serum, plasma, and cell culture supernatant, with optimised protocols.
- Intact: Exosomes can be eluted intact preserving internal cargo.
