<p>This invention relates to a diagnostic method for detecting the presence of a first antigen in a sample in which binding of the first antigen to a first antibody antigen binding site causes release of a second, reporter, antigen from an adjacent second antibody antigen binding site, characterized in that the released reporter is moved away from the antibody and causes the production of a detectable signal at a remote second site. The invention also provides apparatus for performing the diagnostic method of the invention.</p> |
