Latex for immobilization of physiologically active substance and latex reagent using the latex.

摘要

A latex for immobilization of a physiologically active substance and a latex reagent using the latex are disclosed. The latex is prepared by copolymerizing a monomer mixture comprising: (a) 100 parts by weight of an aromatic vinyl monomer; (b) 0.01 to 5 parts by weight of a vinyl monomer having a sulfonic acid group; (c) 1 to 20 parts by weight of an alpha , beta -unsaturated carboxylic acid monomer; and (d) 0.05 to 5 parts by weight of a polyfunctional monomer for internal cross-linking; in water using a water-soluble radical polymerization initiator in the absence of an emulsifying agent.
