The Pros and Cons of Horseradish Peroxidase Assay (HRP) Testing

Horseradish Peroxidase (HRP) Assays detects horseradish peroxidase enzymatic activity by color change

by | Aug 22, 2023

Horseradish peroxidase (HRP) assays are a versatile laboratory testing tool that can be used to detect and quantify specific molecules and enzymatic activity of horseradish peroxidase. The presence of horseradish peroxidase causes color change. This color change enables a wide range of biological, chemical, and environmental processes to be observed and studied. Like any laboratory technique, however, HRP assays come with their own set of pros and cons that researchers must consider before choosing horseradish peroxidase as their testing method.

Pros of Horseradish Peroxidase (HRP)

HRP assays are notable for their sensitivity. This sensitivity makes them able to detect even minute quantities of target molecules. This feature is particularly advantageous in applications where high sensitivity is essential, such as medical diagnostics and environmental monitoring. HRP assays can also be applicable in a wide range of applications, and find utility in various research areas, including immunology, molecular biology, and biochemistry. HPR assays are used in enzyme-linked immunosorbent assays (ELISA), Western blotting, and other techniques that require the detection of specific proteins or molecules. The enzymatic reaction catalyzed by horseradish peroxidase leads to signal amplification, resulting in higher signal-to-noise ratios. This amplification enhances the accuracy and reliability of experimental results.

Cons of Horseradish Peroxidase (HRP)

One challenge associated with HRP assays is the potential for non-specific binding, where the enzyme might interact with unintended molecules, leading to false-positive results. Stringent controls and optimization are required to mitigate this issue. Similarly, despite their sensitivity, HRP assays can sometimes be susceptible to background noise, which may impact the accuracy of measurements. Researchers need to carefully design their experiments to minimize background interference. Implementing HRP assays can be complex and require careful optimization of various parameters such as concentrations, incubation times, and reagent compatibility. This complexity can extend the experimental timeline and demand a deeper understanding of enzymatic reactions. HRP assays can be relatively expensive due to the need for specialized reagents and equipment. Researchers should evaluate the costs and benefits before committing to these assays.

How Contract Laboratory Helps with Horseradish Peroxidase Assay HRP Testing

Contract Laboratory has helped companies find laboratories to perform their horseradish peroxidase HRP testing. Below are some examples of Laboratory Requests that we have received:

  •  Australia ISO 17025 Accredited Laboratory needed for determination and quantification of Hydrogen Peroxide generating capacity of honey using horseradish peroxidase assay.
  • Contract Laboratory needed for Hydrogen Peroxide generation testing in honey. Horseradish Peroxidase Assay required as part of testing
  •  GLP Bioanalytical laboratory is needed for western blot testing with HRP (Horseradish peroxidase) and ECL (Chemiluminescence) detection. In this method, light emission from the HRP-linked secondary antibody is detected using blue-light sensitive X-ray film (λmax = 428 nm). This would need an image station with a film development option.
