The invention relates to an amplification-free method of screening groups of radioactive molecules, comprising at least the following steps: (1) the group of molecules is administered to at least one animal; (2) at least one of the animals is slaughtered and the tissue distribution of the radioactivity of the molecules administered is analyzed in vivo; (3) sections of tissue or organs in which a radioactivity signal is detected are selected; (4) radioactive fractions from the sections of tissue or organs are isolated using suitable techniques such as chromatography and/or extraction techniques; and (5) the molecule(s) from the radioactive fractions obtained in step 4 are characterized using suitable analysis techniques such as chromatography and/or mass spectrometry.
