Reversible immune-assay biosensor

 

Basis:       Equilibrium of 2 binding systems = 2 ABs

 

                  Analyte and labeled Analyte-analogon compete for

                  the binding site of the two ABs

 

note !        AB 1 recognizes the analyte and the analogon!

                 AB 2 recognize only the analogon !
