Better denaturant than SDS?

[Christian Belanger]

Hi netters,

I want to stop enzymatic reaction without using heat.  I work under in situ
condition with raw material.  Heating extract a lot of unwanted stuff.  I
used SDS as denaturing agent but it's a bit too foamy.  Any suggestion on
better denaturing agent?  Any other idea on stopping enzymatic reaction
under in situ conditions with raw material?

E-mail me your answers.

Thank's.
