Abstract
The present disclosure provides a particle showing a small non-specific adsorption, having a reactive functional group for chemically bonding a ligand thereto, and being suitable for an agglutination method; a particle for the agglutination method having a ligand chemically bonded to the particle; a reagent, a kit and a method for detecting a target substance, each for in vitro diagnosis, each of which contains the particle. The particle includes a polymer having a unit having a linker A in a side chain, wherein when both terminals of the linker A are represented by X1 and X2, the linker A has a reactive functional group for chemically bonding a ligand thereto in one of X1 and X2; one of X1 and X2 includes an ester structure; and a sum of bonds between atoms linearly connecting X1 and X2 is 18 to 24 and the X1 and X2 contain CH2 or CH.
