双信号电化学法检测金雀异黄素对MCF-7细胞的抑制作用

Detection of the inhibition of Genistein for MCF-7 by two signals electrochemical method

目的：电化学法研究金雀异黄素对MCF-7的抑制作用.方法：采用双信号电化学法.结果：在10×10-6～120×10-6μM的剂量范围内,随着金雀异黄素剂量的增加,MCF-7的两个电化学信号呈现下降趋势.结论：MCF-7的两个电化学信号均具有金雀异黄素剂量依赖性,说明采用双信号电化学法可以很好地反映金雀异黄素对MCF-7细胞的抑制.

Objective： Studying the inhibition of Genistein for MCF- 7 by electrochemtcal methocl. Method： Two signals electrochemical method was employed. Results： In the dose range of 10× 10-6-120× 10-6μM, with the increasing of genistein dose, two electrochemical signals declined. Concl usion ： Two electro- chemical signals of MCF-7 have dependence of genistein dose. It indicates that the inhibition o（ Genistein for MCF-7 can be well described by two signals electrochemical method.
