WebNov 20, 2024 · Conclusion. We have demonstrated double staining using two HRP substrates as chromogens. The HRP activity from the first staining can be completely removed by a sulfuric acid block step. Using the HRP Magenta chromogen in combination with DAB makes fully automated protocols for double staining possible. WebHorseradish peroxidase (HRP) is a 44-kDa protein that catalyzes the oxidation of substrates in the presence of hydrogen peroxide, resulting in a colored product or the release of light as one product of the reaction (chemiluminescence). HRP functions optimally at a near-neutral pH and can be inhibited by cyanides, sulfides and azides.
