[EtBr] measurements????

[The Kindly One]

Does anyone know of a method to roughly determine how much
EtBr is in a solution? Possibly somethign spec wise?

I'm just tired of staining for 20 minutes only to discover t
that the "staining colution" shared by many people has been
depleted of EtBr.

Thanks
