[Histonet] Hydrogen Peroxide for IHC

[Lee & Peggy Wenk]

We use "store bought". However, we buy it through our hospital pharmacy, so
it comes in fresh and cheaper than off the drug store shelf. Plus, we look
at the expiration date (which is always a year down the road).

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

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
