Effect of Tween 80 on the Stability and Conformation of Telomeric G-Quadruplex DNA

Abstract

G-quadruplex DNA is formed in telomer. It inhibits telomerase enzyme which is found active in more than 85 % of cancer cells. In this work, the effect of Tween 80 on telomeric G-quadruplex DNA, AGGG(TTAGGG)3 was studied using circular dichroism spectroscopic technique. The obtained results showed that using Tween 80 with telomeric quadruplex is safe up to less than 1.0 %.
