HRP-polymer secondary antibodies


Use HRP-polymer secondary antibodies to save time, get higher sensitivity and eliminate endogenous biotin background in your immunohistochemistry (IHC) experiments.

HRP-polymer secondary antibodies use micropolymer technology to form smaller detection complexes that allow better tissue penetration and sensitivity. In addition, HRP-polymer secondaries bind more horseradish peroxidase than standard HRP secondary antibodies, increasing signal.

​See why HRP-polymer secondaries are the gold standard for IHC





Additional steps for biotin blocking may be required

On average 1 hour less

Simplified protocol means quicker results with HRP-polymer secondaries.

Higher number of HRP molecules bound to HRP-polymer antibodies increase their sensitivity


Potential background from endogenous biotin

No background from endogenous biotin 

Using HRP-polymer secondary antibodies eliminates biotin background.

Great for tissues with high biotin.
