[Affinity constant in radioimmunoassay].
Values for the affinity constant were determined, in three kits, for seric gastrin, following the Scatchard plot and Michaelis-Menten representation. The determination of the affinity constant, K, is of great value for it defines the antigen-antibody complex stability and it gives information about some aspects of the analysis system: sensitivity and antibody saturation.
