Patent number: 11104904Abstract: An object of the present invention is to provide a convenient and low-cost method for enhancing the stability of a DNA aptamer and/or its capacity to bind to a target molecule, and a DNA aptamer obtained by the method. The object is solved by substituting an internal hairpin structure (stem-loop structure) of the DNA aptamer with a structure called mini-hairpin structure and optionally increasing GC pairs in a stem portion of the DNA aptamer.Type: GrantFiled: July 24, 2019Date of Patent: August 31, 2021Assignee: Tagcyx BiotechnologiesInventors: Ichiro Hirao, Michiko Hirao, Kenichiro Matsunaga

Patent number: 10610889Abstract: The present invention relates to a method for forming a multilayer coating film, the method comprising sequentially applying a colored coating composition (X), an effect pigment dispersion (Y), and a clear coating composition (Z) to a substrate to form an uncured colored coating film, an uncured effect coating film, and an uncured clear coating film, respectively, and heating the uncured colored coating film, the uncured effect coating film, and the uncured clear coating film to simultaneously cure these three coating films, thereby forming a multilayer coating film; wherein the effect pigment dispersion (Y) contains water, a specific surface modifier (A), a flake-effect pigment (B), and a viscosity modifier (C); and a film obtained by applying the effect pigment dispersion (Y) to a dry film thickness of 0.2 ?m has a light transmittance at a wavelength of 550 nm of 10 to 50%.Type: GrantFiled: July 29, 2016Date of Patent: April 7, 2020Assignee: KANSAI PAINT CO., LTD.Inventors: Masayuki Itoh, Kenichiro Matsunaga, Yosuke Toyoda, Tatsuo Kuramochi, Nobuhiko Narita
