Since EtBr is light-sensitive, wouldn't it be sufficient to keep EtBr
waste in a white glass container on the window-shelf or near the
bactericidal UV-light for a couple of days (?weeks) and EtBr would get
Another question: Is EtBr which gets destained (looses its red colour)
Thanks in advance for your replies.
