Abstract
The complexing of an antibody-antigen binding pair is determined by observing the change in fluorescence of a pH-sensitive fluorochrome attached to one of the members of the binding pair. When the binding is conducted in a solution having a pH other than the isoelectric point of the antibody, there will be a change in the pH of the microenviromnent surrounding the fluorochrome. This change will correspond to a change in the observed fluorescent intensity. Either member of the binding pair can be labeled, and combined with that member whose presence is suspect, in an immunoassay.
