微量波动实验是1978年由Gathonse建立的一种筛选致突变物的实验方法。我们对此实验的影响因素进行了探讨.我们进行有无S9存在时,组氨酸、生物素浓度的正交实验。以自发阳性孔数10左右为依据选择出无S9时,组氨酸浓度为1.6ug/ml。生
The trace fluctuation experiment is an experimental method of screening mutagens established by Gathonse in 1978. We investigated the factors that affect this experiment, and we conducted orthogonal experiments with histidine and biotin concentrations in the presence and absence of S9. To the number of spontaneous positive holes of 10 or so based on the choice of no S9, histidine concentration of 1.6ug / ml. Health
