RE: sodium azide: how to prepare a buffer from the powder?

Dear Florent - We use 10% sodium azide for our standard buffer, and we
make it up with powdered sodium azide.	We have never had a problem,
although we're not supposed to dispose of it by pouring it down the
drain.	We do put a warning label on the 10% solution and the buffer.

Hope this helps -

	Dear all,
	 
	this is not strictly speaking a flow cytometry question but more
of a chemistry question. I have purified antibodies on a column and I
would like to store them in a buffer containing sodium azide. I ordered
the powder but reading the MSDS, it seems impossible to use it as it is
incompatible with water and explodes. How do you do to put sodium azide
powder in a buffer solution?
	Thank you in advance.
	 
	Best regards
	 
	Florent
