摘要
Conjugates of peptide nucleic acids (PNA) and metal binding ligands were prepared using solid-phase synthesis. Stability of duplexes of bis-picolylamine-PNA conjugates and DNA was found to be modulated by equimolar concentrations of bioavailable metal ions: Ni2+, Zn2+ > Cu2+. Sequence specificity of PNA was not compromised in the presence of these metal ions. (C) 2003 Elsevier Science Ltd. All rights reserved.
