Circular dichroism was used to study changes in conformation of poly(dA-dC).poly(dG-dT) caused by a high concentration of various monovalent salts. It was found that CsF induced the gradual appearance of a negative band in the long wavelength part of the CD spectrum of poly(dA-dC).poly(dG-dT), which might reflect a transition of this DNA toward a Z-like structure.
利用圆二色性研究了高浓度各种单价盐引起的聚(dA-dC)·聚(dG-dT)构象变化。发现CsF能使聚(dA-dC)·聚(dG-dT)的圆二色光谱长波长部分逐渐出现一个负峰,这可能反映了该DNA向类Z结构的转变。
