  • derived composition for detecting peptidoglycan, a method for use thereof, and a diagnostic kit containing the same
    Patent number: 7507553
    Abstract: The present invention relates to a composition for selectively detecting an extremely small amount of peptidoglycan in sample, a preparation method of the composition, and a detection kit for peptidoglycan. It is possible to quantify a small amount of peptidoglycan contained in human blood, tissue, body fluid, water or food, and to diagnose an infection of microorganism with peptidoglycan as a component of cell wall using the composition and the detection kit. In addition, the composition can be applied for a diagnosis reagent of detecting an infection of Gram-positive bacteria in animal or human being in advance, and thus, can be used for the prevention or treatment of food poisonings and bacterial sepsis.

  • Composition for detecting ?-1,3-glucan
    Patent number: 6987002
    Abstract: The present invention relates to a composition for detecting an infinitesimal quantity of ?-1,3-glucan, a preparation method thereof and a diagnostic kit detecting ?-1,3-glucan. The composition of the present invention shows phenoloxidase activity by ?-1,3-glucan in the presence of calcium ions. Using the composition of the present invention, a sample is gathered from a specimen, the composition of the present invention and calcium ions are added to the sample, and ?-1,3-glucan is detected by measuring phenoloxidase activity.
