The Fab fragments of antibodies against cell-type-specific surface antigens of mouse mammary epithelial cells (MME-antigens) were used to localize mammary tumors successfully. The radioiodine-labeled anti-MME (Fab) was injected into mice carrying simulated mammary metastases, and after 24 hours the amount of label per gram of excised tissue was several times greater in the tumor than in liver, brain, lung, or muscle. With a high-purity germanium camera, mammary tumors were clearly located by the /sup 131/I-labeled anti-MME (Fab), and normalization to /sup 99m/Tc-pertechnetate distribution in the animal increased the specificity. The density of /sup 131/I-label was fourfold greater over the mammary tumor than over comparable areas of the mouse. No accumulation of /sup 131/I-anti-MME (Fab) was observed in nonmammary tumors nor in mammary tumors when labeled nonspecific Fab was used.
