Exosomes are specific subclasses of extracellular vesicles that convey critical information in the form of small RNAs, mRNAs, bioactive lipids, and proteins. As a key mediator in cell-cell communication, exosomes play an important role in many aspects of physiology and disease. Exosome characterization offers tremendous clinical opportunities in the field of liquid biopsy. Realizing this potential requires the detection and characterization of exosomes with high precision and reproducibility, which is challenging for any project or study. Lifeasible provides customers with all the experience and technical capabilities in the field of exosomes to facilitate a comprehensive analysis of exosomes.
Exosomes are prone to residual contaminants of the non-vesicular structure during purification, characterization of multiple aspects of purified exosomes is critical for their use in downstream experiments. The International Society for Extracellular Vesicles (ISEV) recommends three aspects for the isolated exosomes: size, morphology, and surface markers. In addition, a comprehensive exosome contents analysis can be performed through high-throughput sequencing, protein profiling, and metabolomic analysis.

Lifeasible has developed and implemented several characterization and validation methods for research and clinical purposes, allowing the analysis of purity and composition and quantification of exosomal samples. The following are techniques for analyzing exosome size, morphology, surface markers, and endosomes.
