1·OBJECTIVE to set-up safe alternatives to ethidium bromide (EB).

目的建立比溴化乙锭(EB)更为安全的核酸染色方法。

2·The amount of transferred RNA was estimated using the ethidium bromide staining method.

样本加样RNA量用溴化乙锭染色法评估。

3·The PCR products were analyzed by electrophoresis in agarose gels stained with ethidium bromide.

扩增产物用琼脂糖凝胶电泳、溴化乙锭染色检测。

4·The cytotoxicity and DNA cross links of the cells were detected with MTT assay and ethidium bromide fluorescence assay.

采用四氮甲基唑蓝比色法、溴乙锭荧光法检测肺细胞的生长情况和DNA交联的形成。

5·Methods: DNA damage was measured by the loss of fluorescence after DNA binding to ethidium bromide and by the increased DNA mobility in agarose gel electrophoresis.

方法：通过DNA结合溴乙锭后的荧光损失和DNA琼脂糖凝胶电泳的迁移率来测定dna的损伤程度。
