Abstract: A method for producing an intermediate antibody regioselectively modified, which comprises:



(1) mixing a solution comprising an antibody material and a solution comprising a reagent for regioselectively modifying an antibody in a micromixer to form a mixture comprising the antibody material and the reagent,
wherein the reagent comprises a compound comprising an affinity substance to an antibody and a reactive group to an antibody; and
(2) passing the mixture through a reaction channel to allow the antibody material and the reagent to react in the reaction channel to form a solution comprising an intermediate antibody regioselectively modified,
wherein the processes (1) and (2) are continuously performed in a flow microreactor,
is capable of rapidly producing a desired antibody derivative regioselectively having a functional substance or functional substances.
