Description

EP Block, blocking Reagent is a highly stable form of hydrogen peroxide for blocking endogenous peroxidase. It is very effective for blocking non-specific staining in IHC. It is more preferable over other formulations of peroxide block.

In IHC procedures, non-specific or high background staining may occur in some cells or tissues due to endogenous peroxidase activity. This non-specific background can be significantly reduced by pre-treatment of cells/tissues with hydrogen peroxide prior to incubation with HRP conjugated antibody. BioMarq EP Block provides irreversible blocking of endogenous peroxidases. EP-Block is non-flammable, safer and less toxic when compared to hydrogen peroxide/methanol formulations.
