Nonenzymatic ligation of oligodeoxyribonucleotides on a duplex DNA template by triple-helix formation

open access: yes, 1989
We report that a double-stranded DNA template can direct the sequence-specific formation of a phosphodiester linkage between oligodeoxyribonucleotides in aqueous solution by juxtaposing the termini head-to-tail in a triple-helical complex (Figure 1).

The Reactivity of the 5-Hydroxy-5,6-dihydrothymidin-6-yl Radical in Oligodeoxyribonucleotides

open access: yes, 2016
Hydroxyl radical can be induced from Fenton reaction or γ radiolysis of water. It can add preferentially to the C5 position of thymidine to give the 5-hydroxy-5,6-dihydrothymidin-6-yl radical.

Synthesis of oligodeoxyribonucleotides from 3'-O-formyl-(N-acyl)-2'-deoxyribonucleosides using o-chlorophenylphosphoditriazolide and/or methyl phosphodichloridite. Removal of methyl group from phosphotriester by the action of aqueous pyridine

open access: yes, 1983
d-GGAATTCC (XI) was prepared by phosphomonotriazolide method in solution. Synthesis of oligodeoxyribonucleotides by phosphite method in solution using methyl phosphodichloridite was studied. Preparation of P-methyl esters of protected d-CA (XVII), d-CAT (

A further contribution to the extreme variability of quadruplex structures from oligodeoxyribonucleotides containing inversion of polarity sites in the G-tract

open access: yes, 2008
Structural insight into DNA quadruplex structures formed by oligodeoxyribonucleotides 3'TG5'-5'GGGT3' (QS55) and 5'TG3'-3'GGGT5' (QS33) is presented. NMR anal. reveals that QS33 forms a parallel-like four-fold sym.

Ef®cient methods for attaching non-radioactive labels to the 5¢ ends of synthetic oligodeoxyribonucleotides

open access: yes, 1986
The syntheses are described of two types of linker molecule useful for the specific attachment of non-radioactive labels such as biotin and fluorophores to the 5 ' terminus of synthetic oligodeoxyribonucleotides.

Phosphodiester-Mediated Reaction of Cisplatin with Guanine in Oligodeoxyribonucleotides

open access: yes, 2016
The cancer chemotherapeutic agent cis-diamminedichloroplatinum(II) or cisplatin reacts primarily with guanines in DNA to form 1,2-Pt-GG and 1,3-Pt-GNG intrastrand cross-links and, to a lesser extent, G-G interstrand cross-links.

Fluorescence microscopic comparison of the binding of phosphodiester and phosphorothioate (antisense) oligodeoxyribonucleotides to subcellular structures, including intermediate filaments, the endoplasmic reticulum, and the nuclear interior

open access: yes, 1997
To detect potential intracellular binding sites for antisense oligodeoxyribonucleotides (ODN), 3'−fluorescence−tagged phosphodiester (P) and phosphorothioate (S) analogs of a series of model and vimentin and actin antisense ODN were applied to ...

Study on the Electrophoretic Behaviour of Short Oligodeoxyribonucleotides in Fused Silica Capillaries. A Preliminary Communication

open access: yes, 2015
Effects of background electrolyte pH, composition and concentration on the electrophoretic transport of short oligodeoxyribonucleotides (ODNs) in fused silica capillaries have been investigated in the presented study.

Thermal elution of oligonucleotides on cellulose columns containing oligodeoxyribonucleotides of defined length and sequence

open access: yes, 1970
The high degree of specificity of base interactions of complementary polynucleotides is a fundamental property of biological systems. Through interactions of this type, genetic information is able to flow, to succeeding generations by replication of the ...
