Electrical conductivity in some biopolyelectrolytes

The electrical conductivity data, collected at 100 kHz, of several pure water biopolyelectrolyte solutions in the three decade wide range of cDNA from 0.01 to 15 mg/mL are presented. Two solution regimes are studied: semidilute regime for long double-stranded Na-DNA, long single-stranded Na-DNA and long Na-HA, and dilute regime for 146 bp Na-DNA. Contributions from free and condensed intrinsic counterions, as well as from polyions are discussed, and a comparison with the experimental data is given.
