    摘要: Provided is a polishing composition containing at least aluminum oxide abrasive grains and water, and having a pH of 8.5 or higher. The aluminum oxide abrasive grains have a specific surface area of 20 m2/g or less. It is preferable for the aluminum oxide abrasive grains to have an average secondary particle size of 0.1 μm or more and 20 μm or less. The polishing composition is used for polishing hard and brittle materials having a Vickers hardness of 1,500 Hv or higher, such as sapphire, silicon carbide, and gallium nitride.

    摘要: A thin membrane for measuring protease activity, which is formed on a support and, which comprises one or more kinds of substances selected from the group consisting of a transferrin derivative and an albumin derivative and is crosslinked and/or substantially water-insoluble. The membrane enables selective measurement of protease activity of a particular class of protease such as matrix metalloproteinase 7.
