Abstract

A purpose of the present invention is to provide a highly sensitive and less expensive lectin-immobilized base material (for example, a lectin plate), said lectin-immobilized base material having stable qualities and being able to be sufficiently washed after a target sugar chain-containing antigen binds thereto. Another purpose of the present invention is to provide a method for immobilizing lectin to a base material therefor. Provided are: a method whereby a lectin-peptide fusion, in which a peptide capable of adsorbing to a base material surface such as a PS tag is fused with the N-terminal side or C-terminal side of lectin capable of recognizing a target sugar chain, is immobilized on the peptide side to a base material; and a lectin-immobilized base material produced by this method. By using the lectin-immobilized base material, a target sugar chain-containing antigen can be highly sensitively and evenly measured and, moreover, target sugar chain-containing cells, etc. can be separated (concentrated and harvested).

Abstract

[Problem] To provide an external skin preparation solid substrate exhibiting high breaking strength and excellent thermal stability, and usable as a stick-shaped substrate or the like. [Solution] An external skin preparation solid substrate containing: a lipid-peptide-type compound comprising one or more types selected from among a compound represented by formula (1), a compound similar thereto, or a pharmaceutically usable salt thereof; a surfactant; water; and a C8-30 saturated or unsaturated monovalent alcohol. (In the formula, R1 represents a C9-23 aliphatic group, R2 represents a hydrogen atom or a C1-4 alkyl group that may have a C1 or C2 branched chain, R3 represents a -(CH2)n-X group, n represents a number from 1 to 4, and X represents an amino group, a guanidino group, a -CONH2 group, or a five-membered or six-membered ring which may have 1 to 3 nitrogen atoms or a condensed heterocycle configured from the five-membered ring and the six-membered ring.)

Abstract

A dermatological adhesive material that is a liquid composition including (a) a copolymer that includes monomer units (I) having a polyalkylene glycol skeleton with a degree of polymerization of 2-100 in a side chain and monomer units (II) having a C3-30 branched alkyl group in a side chain, (b) water, and (c) an oily component, and changes into a gel on the skin. A hydrogel having excellent tight adhesiveness to the skin surface on the skin and adhesiveness to the skin can be formed by applying this dermatological adhesive material to skin.

Abstract

A film-forming composition for ink-jet coating which comprises: a triazine-ring-containing polymer including, for example, the repeating unit structure represented by the following formula [3]; and an organic solvent comprising more than 50 mass% solvent based on a glycol dialkyl ether. The composition is less apt to corrode the heads of ink-jet coating devices, and droplets thereof are satisfactorily ejected in ink-jet coating. Therefore, with the composition, it is possible to easily produce a high-refractive-index film according to a desired pattern through pattern printing by an ink-jet coating device.
