Purified Exosomes

 

Tools for discovery

Exosomes are complex variable structures which require basic characterization as part of any study. Guidance on the minimal level of characterization that should be performed before a study can be published has been provided by the exosome community.  Cell Guidance Systems has developed a range of solutions based on exosome composition and characteristics. These include: exosome marker antibodiesExoLISA™ detection assayInstant Exosomes™ and we also offer an NTA size profiling service.

Instant Exosomes™

Instant Exosomes™ are a range of high-quality and well-characterized freeze-dried exosome samples from human cancer cell lines and stem cells. Exosomes are isolated following a combination of precipitation and size exclusion chromatography (SEC). The exosome samples are characterized for overall protein content, using a BCA assay, expression of commonly expressed exosomal markers (CD9, CD63 and CD81) using the ExoLISA™ exosome detection assay and, particle concentration and size distribution by nanoparticle tracking analysis (NTA) using a Zetaview® instrument from Particle Metrix GmbH.

The ready-to-use exosomes are suitable for a wide-variety of applications, including:

  • Protein biomarker analysis
  • Functional assays
  • Analysis of exosomal nucleic acids
  • Electron microscopy
  • Assay positive controls
