FIGURE 5. Immunoreactivity assay of radioiodinated c-MOv18 MAbs used for biodistribution analysis: 125I-c-MOv18 ({blacksquare}); 131I-c-MOv18, high dose ({blacktriangleup}); 131I-c-MOv18, low dose (•). T/C values (T = total radioactivity; C = activity specifically bound to cells) are function of inverse of cell concentration.
