  • METHOD FOR ISOLATING EXOSOME AND EXOSOME ISOLATION KIT
    Publication number: 20210389314
    Abstract: 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.

  • PROTEIN TAG THAT BINDS TO SUBSTANCES HAVING A CRYSTAL STRUCTURE, AND USES THEREOF
    Publication number: 20190056394
    Abstract: In order to provide a protein tag and use thereof, the present invention uses a protein tag that binds to a substance having a crystal structure and that includes a binding domain whose amino acid sequence is a mutated version of an amino acid sequence of an ice-binding domain derived from an antifreeze protein.

  • Method for selectively culturing microorganism using phosphite dehydrogenase gene as marker
    Patent number: 9499822
    Abstract: 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.

  • Method for detecting asbestos
    Patent number: 9322822
    Abstract: 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.
