Our lab we always used 3% hydrogen peroxide manufactured by Fisher. We were not willing to pay for "brand" 3% H202 like Ventana.

Subject: [Histonet] Hydrogen Peroxide for IHC


Just wondering if anyone has purchased 3% Hydrogen Peroxide in the 500 ml
bottle from the local drug store at $1.00 +/- and used it for IHC instead
of the
$66 bottle from Ventana or similar company? Do you add tween?
thanks....Criss
