Purified horseradish peroxidase enzyme for use in activity assays and conjugation to antibodies for ELISA, Western blot and immunohistochemistry applications.
Commonly used as a second step for detection of biotinylated antibodies by ELISA and western blot. Avidin binds to biotin with high affinity. [Note: Sodium azide is an inhibitor of horseradish peroxidase enzymatic activity and should not be added to the AV-HRP diluent.]
Thermo Scientific™ Pierce Avidin and Conjugates include purified avidin protein from hen egg whites, plus avidin-HRP, avidin-AP and other conjugated forms for use in biotin-based detection methods.
