Abstract
A physiologically active substance-measuring reagent and a method for measuring a substance to be measured using the reagent. The physiologically active substance-measuring reagent comprises particles of a support polymer obtained by radical emulsion polymerization of the components (1), (2) and (3) as described herein above, and a physiologically active substance having an interaction with a substance to be measured, supported on the particles.
Claims5
A physiologically active substance-measuring reagent comprising particles of a support polymer obtained by radical emulsion polymerization of:
- (1) 0.1 to 20% by weight of a radically polymerizable vinyl monomer having a carboxylic group,
- (2) 0.05 to 20% by weight of at least one of a compound represented by the following formula (I):
- CH2═C(R1)CO(OCH2CH2)nOR2 (I)
- wherein R1 represents a hydrogen atom or a methyl group, R2 represents a hydrogen atom, a C1 to C6 alkyl group, an alkoxyphenyl group, a phenyl group, an acryloyl group, or a methacryloyl group, and n represents a number of 2 to 22, and a radically polymerizable vinyl monomer having a strong acid group, and
- (3) 60 to 99.8% by weight of a radically polymerizable vinyl monomer copolymerizable with the monomers (1) and (2), and
- supported on the particles, a physiologically active substance having an interaction with a substance to be measured.
