Description and Specification


Formulation Proprietary buffered solution containing peroxide (H2O2)
Sufficient For 1L of 1X buffer with appropriate peroxidase substrate
Description Pierce Stable Peroxide Buffer, 10X
Quantity 100mL

The Stable Peroxide Substrate Buffer is an ideal formulation for researchers who prefer to make their own horseradish peroxidase (HRP) substrates. The substrate is easily prepared by adding the chosen chromogen to a 1X solution of the Stable Peroxide Substrate Buffer, which supplies the needed peroxide and buffer condition to obtain optimum and consistent results. This buffer is provided at a 10X concentrate, which allows a shelf life of up to one year. The Diethanolamine Buffer is a 5X stock solution (5.1M, pH 9.8) that provides optimal conditions for development of alkaline phosphatase reactions, such as with PNPP (Part No. 34045, 34047).


  • Ready-to-use concentrated stock solutions
  • Minimize assay-to-assay variability

  • Long shelf life: 12 months after receipt
  • Total volume of 1000mL can be made from one 100mL bottle of concentrate
  • Add chromogen to stable peroxide substrate buffer for detection of horseradish peroxidase

Diethanolamine Substrate Buffer (5X) (Part No. 34064)

  • For use with soluble alkaline phosphatase substrates such as PNPP
  • Optimized, consistent pH
  • Stable even at a 1X concentration
