Using the DNA sequencing technique of Maxam and Gilbert, we show that the protein antibiotic neocarzinostatin, cleaves double-stranded phiX174 DNA restriction fragments almost exclusively at deoxythymidylic and deoxyadenylic acid residues in a reaction requiring 2-mercaptoethanol. Overall, deoxythymidylic acid residues are attacked much more frequently than are deoxyadenylic acid residues, alth...
We describe a highly efficient method for reversible photocircularization of oligonucleotide (ODN) on a double-stranded DNA template: 5-carboxyvinyl-2'-deoxyuridine-containing ODN was reversibly circularized around the target sequence of the double-stranded plasmid DNA resulting in formation of a catenated plasmid.
To develop a covalent and specific labeling method for single- and double-stranded plasmid DNA, photoresponsive oligonucleotide containing 3-cyanovinylcarbazole nucleoside was adopted. Single- and double-stranded plasmid DNA was successfully labeled/de-labeled with Cy3 and/or biotin by photoirradiation.
