  • Publication number: 20240293776
    Abstract: The present invention relates to a method for mass purifying high-purity bacterial extracellular vesicles and, more specifically, the present invention relates to a method for quickly and conveniently isolating and purifying high-purity bacterial extracellular vesicles from a large amount of bacterial cell culture product by means of calcium or cobalt. The purification method of the present invention is appropriate for obtaining high-purity bacterial extracellular vesicles in a commercial scale by treating a large amount of bacterial cell culture product and, particularly, when using calcium which is innocuous to the human body, is more advantageous in purifying bacterial extracellular vesicles to be used in a drug for human body.

  • Patent number: 12057847
    Abstract: A delay circuit including a first output clock generation circuit and a second output clock generation circuit. The first output clock generation circuit generates a first output clock signal by mixing phases of a first clock signal and a second clock signal based on an (n+1)-th generated delay control signal. The second output clock generation circuit generates a second output clock signal by mixing the phases of the first and second clock signals based on both an n-th generated delay control signal and the (n+1)-th generated delay control signal.

  • Patent number: 11904259
    Abstract: The present invention relates to a method for isolating extracellular vesicles using cations, and more particularly, to a method for isolating extracellular vesicles from various samples by using the affinity between the extracellular vesicles and cations. A method for isolating extracellular vesicles according to the present invention does not require expensive equipment, can be applied irrespective of sample amount, and has the advantage of being capable of efficiently isolating the extracellular vesicles while preserving the shape or characteristics thereof. Moreover, the method according to the present invention can be combined with existing isolation methods to maximize extracellular vesicle isolation efficiency, and can be applied to disease diagnosis, disease treatment, and multi-omics research using isolated extracellular vesicles, as well as to research on the properties of extracellular vesicles.
