is there a simple way of testing DAB solution

From:Tibor Ric <> (by way of Histonet)

Hi Everygody!

Here I come with (maybe a stupid) a question.

Me and my friends at our lab wonder if there is a simple way of testing our
DAB solution. I mean is it possible to check if the DAB solution still is
working without setting up an application?

Is there some chemical way of testing?

Thanks in advance!
