Abstract: Controlled release particles are obtained by dissolving a hydrophobic antibiotic compound with a hydrophobic polymerizable vinyl monomer to prepare a hydrophobic solution, blending water with an emulsifier to prepare an aqueous emulsifier solution, emulsifying the hydrophobic solution in the aqueous emulsifier solution, and polymerizing the polymerizable vinyl monomer by mini-emulsion polymerization in the presence of a polymerization initiator, thereby producing a polymer containing an antibiotic compound and having an average particle size of below 1 ?m.

Abstract: A controlled release particle includes a core containing an antibiotic compound, and a shell covering the core. The controlled release particle is obtained by a production method including a first step in which a first component containing an antibiotic compound and a polymerizable vinyl monomer is subjected to suspension polymerization to form the core containing the antibiotic compound and a polymer of the polymerizable vinyl monomer; and a second step in which a second component containing a shell-forming component is subjected to interfacial polymerization to form a shell, wherein in the second step, the interfacial polymerization is started simultaneously with the start of the suspension polymerization of the first step, or started after the start of the suspension polymerization of the first step.

Abstract: The present invention provides for a method of selecting an antibody against a target substance to be measured, which comprises selecting the antibody against the target substance by antigen-antibody reaction in the presence of a substance interfering with the antigen-antibody reaction. That is, an antigen and a labeled antigen are reacted with the antibody in the presence of an interfering substance, such as an environment pollutant, and on the basis of the degree of reaction thereof, the antibody against the target substance, which is highly resistant to the interfering substance, is selected. Thereby, even if a test sample is contaminated with a substance interfering with antigen-antibody reaction, the antibody, which is highly resistant to the substance interfering with antigen-antibody reaction, is not influenced by the interfering substance and gives a correct value in the quantification.
