Molecular models of the mono-, di- and tetrameric Ac-TZ14011 dendrimers with the MSAP label. For clarity, the MSAP label is not colored by element: the CyAL-5.5b fluorophore is displayed in red, the indium-bound DTPA chelate in blue and the spacer in grey. In the dimer and, especially, in the tetramer a smaller percentage of the whole molecule comprises the MSAP label.
