Beschreibung

Allgemeine Beschreibung

Poly(deoxyguanylic-deoxycytidylic) acid (poly(dG-dC)) undergoes salt dependent conformational transition. Under high-salt, it exists as a left-handed double helix and at low-salt it displays B-DNA conformation. However on immobilization, poly(dG-dC) takes up A DNA form.

Anwendung

Poly(deoxyguanylic-deoxycytidylic) acid (Poly(dG-dC) • Poly(dG-dC)) is an alternating copolymer, self-complementary, double-stranded DNA model for conformational studies of DNA structure dynamics and drug interaction.

Poly(deoxyguanylic-deoxycytidylic) acid sodium salt has been used:

• in electrophoretic mobility shift assay of transcription factor IIIB complex
• as synthetic copolymers for circular dichroism (CD) spectroscopy studies
• as a positive control in liquid scintillation counting
