- Used with pNPP tablets to create a working phosphatase substrate
- Stabilizes pNPP in solution
- Convenient liquid concentrate
DEA buffer is used to dissolve pNPP tablets and prepare a working solution of pNPP Microwell Substrate. The working substrate develops a soluble yellow product and is used to detect alkaline-phosphatase conjugates. The substrate reaction can be stopped with an equal volume of APStop™ Solution.
