Description
Horseradish Peroxidase (HRP) is used in a wide range of liquid clinical chemistry reagents, dry powder reagents and test strips. It is also commonly used as a label in immunoassays such as ELISA, and in blotting and histochemistry. Once conjugated to antibodies, antigens, or streptavidin, its rapid turnover rate gives high sensitivity over short incubation times. Peroxidase conjugates may give higher backgrounds than other enzyme conjugates, hence extra blocking steps, e.g. the introduction of APO Peroxidase, may be necessary. It can be used with a variety of substrates producing precipitated or soluble chromogens, or with chemiluminescent and fluorogenic substrates for enhanced sensitivity
