摘要
g -四重体DNA在端粒体中形成。它能抑制端粒酶,这种酶在85%以上的癌细胞中都很活跃。本文利用圆二色光谱技术研究了Tween 80对端粒g -四重体DNA AGGG(TTAGGG)3的影响。结果表明,端粒四重体使用Tween 80的安全性不超过1.0%。
Effect of Tween 80 on the Stability and Conformation of Telomeric G-Quadruplex DNA
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 %.
