用拉曼光谱对抗胃腺癌IRNA组分Ⅰ~Ⅴ进行了拉曼光谱分析,结果证明IRNAⅠ、Ⅱ的拉曼光谱不同于其它RNA。在低盐浓度下,IRNAⅠ、Ⅱ兼有A和Z型构象,而IRNAⅢ~Ⅴ呈A型构象。
Raman spectroscopy analysis of Raman spectroscopy against gastric adenocarcinoma I RNA components I-V showed that Raman spectra of IRNAI and II were different from other RNAs. At low salt concentrations, IRNAI and II both have A and Z conformations, whereas IRNAIII to V assume A conformation.
