Re: DMSO vs. glyOH 

 I have used 7% DMSO 	for several years added directly  to a freshly saturated 
culture and have found  it every bit as good if not better than glycerol for freezer stocks.
	Its certainly easier to pipet.  		Cheers!

Anybody who has experience with DMSO instead of glycerol? (I use it,
but I haven't rigorously compared it with glycerol.)
