Abstract: Provided is a resin composition for an acoustic matching layer, the resin composition including metal particles (A), an epoxy resin (B), a polythiol compound (C), and a cure-accelerating compound (D). The epoxy resin (B) includes at least one epoxy resin selected from the group consisting of bisphenol A epoxy resins, bisphenol F epoxy resins, and phenol novolac epoxy resins, and the polythiol compound (C) includes a compound having at least two specific partial structures. Also provided are a cured product formed of the composition, an acoustic matching sheet, an acoustic probe, an acoustic measuring apparatus, and a method for producing an acoustic probe. Further provided is an acoustic matching layer material set suitable for preparation of the composition.

Abstract: An object of the present invention is to provide a kit, a method, and a reagent which prevent the problem of false positive due to nonspecific adsorption, suppress the increase in noise to be generated, and are capable of achieving high-precision measurement of a measurement target substance in a wide concentration range from a low concentration to a high concentration. According to the present invention, there is provided a kit for measuring a measurement target substance, the kit including: a first particle having a label and modified with a first binding substance; a second particle having no label and modified with a second binding substance; a flow channel for flowing the first particle and the second particle; and a substrate having a third binding substance capable of specifically binding to the measurement target substance or a substance capable of binding to the first binding substance, in which the first particle having a label is a luminescent labeled particle containing at least one kind of compound represented by Formula (1) and a particle. Each symbol in Formula (1) has the meaning described in the present specification.
