Ethidium bromide(EBlack Eye is a potent mutagen that has been used for many years as a nucleic acid stain. This material fluoresces a red-orange color under ultraviolet light and with increased fluorescence when bound to double-stranded DNA. Ethidium bromide is typically purchased in powder or solution form and is soluble in water. The crystal or powder form is odorless and appears dark red in color.
The powder form is considered an irritant to the upper respiratory tract, eyes and skin. Ethidium bromide is strongly mutagenic, causing living cell mutations. Even though there is no evidence at this time of human carcinogenicity or teratogenicity, this material should be considered a possible carcinogen or teratogen.
我觉得大家没有必要对EB谈虎变色一样，我也曾看过一位老教授写的view，他说他经常裸手抓胶的，只有学生在的时候才示范性的戴一下手套。当时我看时都吃了一惊，但听他一解释，也觉得有点道理的。 他说，EB如果接触到你的皮肤，一般都是手了，其伤害的都是表皮细胞，而这只是一层死亡了的细胞，其伤害很难达到真皮层。
上面的英文是我从google里搜索到的， 最后一句表明EB should be considered a possible carcinogen or teratogen。
至于大家以后怎么对待他，看自己怎么认为了， 但是我想，坏了手套后至少应该没有感到那么恐慌了！
