The synthetic DOX-LNA conjugate was characterized by proton nuclear magnetic resonance and mass spectrometry. In addition, the purity of the conjugate was analyzed by reverse-phase high-performance liquid chromatography. The cellular uptake, intracellular distribution, and cytotoxicity of DOX-LNA were assessed by flow cytometry, fluorescence microscopy, liquid chromatography/electrospray ionization tandem mass spectrometry, and the tetrazolium dye assay using the in vitro cell models. The DOX-LNA conjugate showed substantially higher tumor-specific cytotoxicity compared with DOX. Crown Copyright (C) 2009 Published by Elsevier Ltd. All rights reserved.
