title: Synthesis of DNA-peptide conjugates by solid-phase fragment condensation.
abstract: [reaction: see text] DNA-peptide conjugates were synthesized by condensing partially protected peptide fragments and oligonucleotides on a CPG support using diisocyanatoalkane as a linker. After cleavage and deprotection with aqueous ammonia, pure products were obtained by single RPHPLC purification in satisfactory yields and identified by a MALDI-TOF MS spectrometer. This method allows one to prepare DNA-peptide conjugates with any components and sequences of DNA and peptides.
