'It seems quite easy; a monoclonal antibody attaches to the cell surface antigen, it gets internalized, the warhead is released, and the cell goes through, apoptosis, and gets destroyed,' added Levy...'There's immunohistochemistry, which looks at just expression on the surface [of cells],' Alexander I.
