Polydeoxyguanylic acid • Polydeoxycytidylic acid (Poly(dG) • Poly(dC)) is a high molecular weight double-stranded homopolymer DNA model compound used for conformational studies of DNA structure dynamics and drug and small molecule interactions.
Other Notes
High molecular weight double-stranded homopolymer
Unit Definition
One unit will yield an A260 of 1.0 in 1.0 ml of 20 mM sodium phosphate/100 mM NaCl, pH 7.0 (1 cm light path).
Reconstitution
Polymers composed of dG and dC can be difficult to dissolve. The recommended dissolution method for poly(dG) • poly(dC) is to suspend the polymer in a minimum of 15 μl per unit in water or buffer and heat to 50-55 °C for 30 minutes with occasional mixing by inversion.
Efficient intercalation of a luminescent Ir(III) complex exclusively made of polypyridine ligands in natural and synthetic biopolymers is reported for the first time. The emission of the complex is largely enhanced in the presence of [poly(dA-dT)(2)] and strongly quenched in

We have compared the behavior in solution of the synthetic polynucleotide poly(dG-m5dC).poly(dG-m5dC) with that of the unmethylated polynucleotide poly(dG-dC).poly(dG-dC). In solutions containing high concentrations of salt, poly(dG-dC).poly(dG-dC) is known to exhibit altered circular dichroic and absorption spectra correlated with formation

The model polynucleotide poly(dG-dC).poly(dG-dC) (polyGC) was titrated with a strong acid (HCl) in aqueous unbuffered solutions and in the quaternary w/o microemulsion CTAB/n-pentanol/n-hexane/water. The titrations, performed at several concentrations of NaCl in the range 0.005 to 0.600 M, were followed

When the model polynucleotide poly(dG-dC)∙poly(dG-dC) [polyGC] is titrated with a strong acid (HCl) in unbuffered aqueous solutions containing the chlorides of the alkali metals in the concentration range 0.010 M-0.600 M, two transitions in the absorbance vs. pH plots are evidenced, characterized
