Lm. Khalimskaya et al., SEQUENCE-SPECIFIC MODIFICATION OF DNA FRAGMENTS BY OLIGONUCLEOTIDE DERIVATIVES CONTAINING ALKYLATING GROUPS AT THE C5 POSITION OF DEOXYURIDINE, Bioorganic & medicinal chemistry letters, 4(8), 1994, pp. 1083-1088
DNA fragments are modified with high efficiency (80-90%) by alkylating
derivatives of oligonucleotides bearing 4(N-2-chloroethyl-N-methylami
no)benzyl group at the C5 atom of the terminal or internal deoxyuridin
e residue. Target modification at a single point is achieved.
