Abstract
Micellular particles such as small unilamellar vesicles of less than 2000 .ANG. loaded with .sup.111 In are administered to BALB/c mice in which EMT6 tumors had been induced. Whole body scintographs of the mice to which either neutral or positively or negatively charged vesicles had been administered show a substantial quantity of the vesicle entrapped .sup.111 In localized in the tumor. Blocking of macrophages in the liver and spleen by first administering unlabeled, aminomannose substituted vesicles before administration of the labeled vesicles increases uptake of the .sup.111 In labeled vesicles in the tumor.
