several physicochemical characteristics of the repeated epitope of the major surface protein ( p30 ) of toxoplasma gondii were investigated with an anti-p30 mab by two different methods : a one-site/inhibition assay that detects molecules containing single or multiple epitopes and a two-site/one antibody radiometric assay that is only effective with antigenic molecules containing two or more identical epitopes .
