Abstract
A particle for a diagnostic agent, which comprises a polymer particle comprising (A) from 20 to 100% by weight of a structural unit derived from at least one of acrylate having an aliphatic hydrocarbon group and methacrylate having an aliphatic hydrocarbon group, (B) from 0 to 10% by weight of a structural unit derived from unsaturated carboxylic acid, and (C) from 0 to 80% by weight of a structural unit derived from a vinyl monomer copolymerizable with the acrylate, methacrylate and unsaturated carboxylic acid, and a turbidmetric immunoassay using the same.
Claims11
A non-magnetic particle for a diagnostic agent, which comprises a non-magnetic polymer particle comprising:
- (A) from 65 to 100% by weight of cyclohexyl acrylate or cyclohexyl methacrylate,
- (B) from 0 to 10% by weight of a structural unit derived from unsaturated carboxylic acid, and
- (C) from 0 to 35% by weight of a structural unit derived from a vinyl monomer copolymerizable with the acrylate, methacrylate and unsaturated carboxylic acid.
