The AP assay system is designed for measuring alkaline phosphatase of various sources (e.g. intestine, placenta, milk, bacteria).

Features and Benefits

  • Sensitive: Approximately 10fg intestinal alkaline phosphatase can be detected
  • High dynamic measuring range: Linear range of more than five orders of magnitude
  • Constant light emission: The assay produces a long-lasting light emission instead of a short peak kinetics


1. Alkaline Phosphatase Substrate, CSPD
2. Enhancer, Emerald II
3. Assay Buffer


CSPD is dephosphorylated by alkaline phosphatase (AP). The resulting instable dioxetane anion decomposes and emits light at a maximum wavelength of 477nm. Chemiluminescence-enhancing reagents improve the quantum yield of the excited state by more than 500 fold.

Preparation Note

Working solution: Preparation of working solution

The substrate reagent is composed of AP-substrate (bottle 1), Enhancer (bottle 2) and Assay Buffer (bottle 3). Prepare substrate reagent freshly before use. The ratio of the components depends on the application. The substrate reagent is stable at least for one day at 2 to 8 °C.

Other Notes

For life science research only. Not for use in diagnostic procedures.
