From: Brook_Milligan@um.cc.umich.edu Not long ago an article in Analytical Biochem. (162: 453-458, 1987) appeared recommending the use of sodium nitrite and hypophosphorous acid as a means of destroying EtBr in solution. Is this a method that others are using currently? What other methods are effective in eliminating the toxicity of such waste? What methods are applicable to decontaminating plastic with EtBr (e.g. trays for staining gels)? What is useful for large quantities of waste generated when staining gels? This issue is of some concern due to the toxicity of EtBr and the result that simply using bleach to destroy it produces more toxic residues. Please respond directly to me and I will summarize the responses to the network. Thanks for any suggestions, help, etc. you may offer.
