Abstract

The porphyrin chromophore incorporated at the 5'-position of an oligonucleotide allows the simultaneous detection of the B- to Z-DNA transition via the porphyrin Soret band circular dichroism exciton couplet signal around 420 nm and the oligonucleotide CD region below 300 nm, at micromolar concentrations.

摘要

掺入寡核苷酸5'-位的卟啉发色团能够通过420nm左右的卟啉Soret带圆二色性激子偶合信号以及低于300nm的寡核苷酸圆二色性区域,在微摩尔浓度下同时检测B型到Z型DNA的转变。
