RNA extraction

[AK]

Let me take a guess, increased proteolysis or decreased protein synthesis or 
both? Let us all know the correct answer to this interesting question, if 
you find it. In your previous lab were you using the same bugs? apparently 
people chill or azide treat the bacteria before RNA prep. Also, it seems 
that azide only works against gram negative bacteria!

I have been told that I have to add sodium azide to my bacterial cultures 
right before the RNA extraction to prevent RNA degradation.  I would like to 
know if anyone knows the basis for this degradation inhibition.  In my 
previous lab we just pelleted and re-suspended in trizol.  Thanks in 
advance.
