Interaction of oligonucleotides with cellular proteins.

Oligonucleotides (ODNs) conjugated to 4-[(N-2-chloroethyl-N-methyl)amino] benzylamine were used to investigate ODN-binding proteins in cells of different origin. The data obtained demonstrate that 68, 46, 38 and 28 kDa ODN-binding proteins are universal for tested cell lines.

5'-bis-pyrenylated oligonucleotides display enhanced excimer fluorescence upon hybridization with DNA and RNA.

A simple one-step procedure was applied for synthesis of oligonucleotide conjugates bearing two pyrene residues at the 5'-phosphate of oligonucleotide. Excimer fluorescence intensity of the conjugates is highly sensitive to duplex formation: binding of the bis-pyrenylated oligonucleotides to their DNA and RNA targets leads 10-fold increase of fluorescence. The data show that excimer fluorescence intensity of the conjugates depends linearly on the concentration of target DNA and permits quantification of DNA in solution.
