[Histonet] PhosphoGuard fixative additive

From:"Connolly, Brett M"

In the June 2008 issue of CAP Today, I ran across a fixative additive
called PhosphoGuard from Targeted Molecular Technologies. 

They claim it prevents degradation of phosphorylated and activated
proteins allowing for better IHC detection (stronger/more abundant
signal) by better inactivation of phosphatases compared to plain 10%
NBF.  Apparently you just add some to your formalin. 

You can check it out further on their website.

Just wondering if any of you have tried it?
