The solution of 0.27% hydrogen peroxide is often used in medical diagnostics and life sciences. It is particularly useful in immunohistochemistry and in blocking endogenous peroxidase activities in tissue sections to avoid non-specific staining.

The solution is particularly suitable for these specific applications because of its ability to act as an oxidizing agent. It helps to disrupt peroxidase activities, minimizing background noise in immunohistochemical assays.

The chemical properties of hydrogen peroxide are based on its ability to act as a strong oxidizing agent. Hydrogen peroxide decomposes into water and oxygen in the presence of catalysts, including peroxidases. This decomposition reaction is exothermic and results in the release of energy in the form of heat.

The operation of the 0.27% hydrogen peroxide solution is based on physical attachment and chemical reaction with peroxidases. This interaction results in the inactivation of peroxidases and prevents non-specific staining in immunohistochemical studies. In combination with other reagents, the solution can help visualize specific antigen-antibody reactions and provide clear visualization.
