摘要:
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.
摘要:
A hybridization carrier, containing a single-stranded polynucleotide having the formula:5'-(dN).sub.n (dT).sub.m -3',wherein N represents admine, guanine or cytosin; T represents thymine; n is an integer of 2 or larger; and m is an integer of 5 or larger;the polynucleotide being immobilized by an amide bond on a surface of an organic polymers particle having a diameter of from about 0.05 .mu.m to about 5 .mu.m;the polynucleotide being immobilized at the site of a nucleotide sequence consisting of 2 or more polynucleotide which contain a primary amino residue in the polynucleotide; andthe amide bond having been formed between the primary amino residue and a carboxyl residue on the surface of the organic polymer particle.
