For which applications is it important to quantitate exosome number?

FAQs Research

For most applications, assessing the relative amount of exosomal protein present (via Western blot or other protein quantification method) is a sufficient indication of the proportion of exosomes present. However, some applications require information about the absolute number of exosomes present in a solution, such as the use of exosomes to deliver therapeutic agents. Quantitation will be an essential step to standardizing the number and size of exosomes selected as cargo delivery particles.
