摘要

A method of preparing an immunological indicator to be chemically bound to antigenic substances, characterized by the operations of contacting microbial cells with molecules of a coupling agent, each of which has at least two unbound reactive groups, making one of said reactive groups forms a covalent chemical bond with said microbial cells, and keep the other of said reactive groups in an unbound state, whereby said indicator is able to react with antigenic substances when put in contact therewith.
