Peroxide Block


Peroxide Block is used to block the endogenous peroxide enzymes that naturally occur in tissue sections. 

Blocking of endogenous peroxidase is a necessary step when performing immunohistochemistry and utilizing a horseradish peroxidase enzyme (HRP) label. If this step is eliminated from the protocol, endogenous peroxide enzymes may cause the chromogen to precipitate, thereby causing background staining to occur.
