Abstract
A coating agent for preventing the adsorption of extracellular vesicles represented by exosomes to a tool has been developed. Adsorption of extracellular vesicles to a tool can be prevented by using a coating agent which contains a hydrophilic polymer having a weight average molecular weight of 10,000 or more and 1,000,000 or less, wherein a coated layer formed by the coating agent has a contact angle of 0 degree or more and 30 degrees or less.
