Ethidium bromide

Ethidium bromide is used for staining DNA. It does not have a harmonised classification. The German "Senatskommission zur Prüfung gesundheitsschädlicher Arbeitsstoffe" of the DFG has classified ethidium bromide to be suspected to be carcinogenic and mutagenic. Suppliers try to lower the hazardous potential by offering the compound as pills or as a ready-to-use-solution. It is well known that dissolved ethidium bromide may penetrate latex gloves. Therefore nitril gloves have to be used.

Substitutes are already described in the WIKIPEDIA-information on ethidium bromide. The company BIOTIUM is offering the substitutes "GelRed" and "GelGreen".
