A process for producing polymer particles having an antigen or an antibody introduced into the surface thereof, by carrying out miniemulsion polymerization using a monomer, a radical polymerization initiator, an emulsifier, and a hydrophobe in the presence of the antigen or antibody to thereby produce the polymer particles, is disclosed. According to the process, it is possible to provide a reagent for immunological analysis having an excellent detection sensitivity and capable of avoiding a nonspecific reaction which occurs in conventional methods.

The present invention provides such a measuring method of the CK isoform and a reagent therefor. Accordingly, the present invention provides a reagent for measuring creatine kinase (CK) activity comprising an antibody, wherein said antibody inhibits CK-M.sub.T subunit, but does not inhibit CK-M.sub.S subunit. The present invention also provides a method for measuring CK activity comprising determining an inhibition of CK of body fluids using a reagent for measuring CK activity, wherein said reagent comprises an antibody which inhibits CK-M.sub.T subunit, but does not inhibit CK-M.sub.S subunit.
