title: A rapid method for the purification of antibody--enzyme conjugates.
abstract: A method is described for a rapid and efficient separation of enzyme-labelled antibodies from the free enzyme following the coupling reaction. A single passage of the reaction mixture on a protein A--Sepharose CL-4B column gave a sharp separation of the free enzyme from the conjugate.
