Re: [Histonet] DAB in tablet form
I too am in academic labs so relate to the cost
concern; however, I strongly recommend DAB in
liquid kit form - either DAB+ from DAKO or from
Zymed. They are liquid ready to use concentrates
diluted into buffer either supplied with the kit
or you provide yourself.
I have used both for years and years now with
excellent results. Worth the extra bucks (about
80-100 dollars for 110 mls which is actually
quite a lot) for consistent results time after
time after time - without the hazards of working
with powder or solids.
