Abstract
In some radioimmunoassays, the antigen competes with labelled antigen for reaction with a first antibody and the antigen-antibody complex is precipitated by reaction with an aqueous solution of a second antibody to the first antibody. The invention consists in using an artificially colored second antibody, so that the precipitate is easily visible to the naked eye.
