[Histonet] H2O2 Recep

[Rene J Buesa]

The bubbling of H2O2 frozen tissue is caused by the chemical destruction of the tissues. 
Do you remember when you apply 3% H2O2 to a skin wound? Don't you remember the bubbling it produces? 
That is the oxygen destruction of the white blood cells that constitute the pus in any wound, as well as the chemical destruction (oxidation) of the live skin cells surrounding the wound.
The addition of methanol does not affect the oxidation of the peroxidase. It is just "a way of doing things" those things that we use to do without any specific (scientific) reason.

So what I'm gathering from all this.

Thanks by the way for the discussion.

Methanol is unnecessary for the H2O2, reaction, but it can make it slightly faster since both methods will be working in concert.  If you have tissue that has more peroxidase than usual, then extra time is required.

Also, If you use straight aq H2O2 on frozen sections the bubbling may damage the tissue.
