Abstract

Immunochemical process of measuring antigenic substances such as human chorionic gonadotropin, growth hormone, insulin, immunoglobulins using a labeled antibody, which makes a monovalent bond to the antigen, and insolubilized antigen. The labeled monovalent antibody used is a monovalent antibody obtained by digesting the antibody to an antigen to be measured with papain according to Porter's method or by reducing a fragment obtained by digesting the antibody with pepsin according to Peterman's method.
