Study on the Interaction of Tetrabromofluorescein and DNA

四 溴 荧光素与DNA作用的研究

The interaction of tetrabromofluorescein ( TBF ) and DNA was studied by the fluorescence and SS - RTP .

用荧光光谱和 磷光 光谱 法研究了 四 溴 荧光素（TBF）与DNA的相互作用。

In the Britton-Robinson buffer solutions of pH 2.35 effective energy transfer could occur between tetrabromofluorescein ( TBF ) and neutral red ( NR ) due to static attraction . The fluorescence intensity of TBF was reduced and that of NR was increased at the same time .

在pH2.35的B-R缓冲溶液中， 酸性 染料 四 溴 荧光素（TBF）与 碱性 染料中性红（NR）之间由于静电吸引能够发生有效的能量转移，使能量 受体NR荧光增强，能量给 体TBF的荧光猝灭。
