The present invention provides a method for simply isolating exosomes from a sample containing exosomes. The present invention includes a complex forming step of forming a complex by binding an exosome in a sample to a particular peptide that contains lysines and is supported on a carrier and a dissociating step of dissociating the exosome from the complex by bringing the complex into contact with a dissociation buffer containing metal cations.

A simple and inexpensive method for selectively culturing a microorganism which method makes it possible to selectively culture a microorganism of interest even without using a sterilization operation or an antibiotic substance is provided. The method according to the present invention selectively culturing a microorganism includes the step of culturing, in a culture medium containing phosphorous acid as a sole phosphorous source, a recombinant microorganism into which a phosphite dehydrogenase gene has been introduced.

In order to provide a method for more efficiently, easily, and accurately detecting asbestos without changing the asbestos detection criterion of the phase-contrast microscope/electron microscope method as compared with the phase-contrast microscope/electron microscope method, a phase-contrast microscope and a fluorescence microscope are used in combination to detect asbestos contained in a test sample after the test sample is made contact with an asbestos-binding protein having a fluorescent label.
