Radioimmunoassay.
Radioimmunoassay is often described in terms of the competition between a radiolabeled antigen (Ag*) and its unlabeled counterpart (Ag) for binding to a limited amount of specific antibody (Ab) (1). In most radioimmunoassays the reaction is allowed to proceed to equilibrium and thus, can be represented by Eq. (1). [Formula: see text].
