摘要
研究了花菁Ⅱ与核酸的相互作用,发现在核酸的存在下,花菁Ⅱ的荧光被明显地猝灭,且猝灭程度与核酸的浓度存在良好的线性关系。
The interaction between cyanine Ⅱ with nucleic acids was studied,cyanine Ⅱ fluorescence quenching was obvious in the presence of nucleic acid,and the degree of quenching and the concentration of nucleic acids showed a good linear relationship.
