pNPP 1-Component AP Microwell Substrate with Stabilizing Pellets is a ready-to-use alkaline phosphatase substrate formulation to detect alkaline phosphatase-conjugated molecules in ELISA and microwell assays.
Alkaline phosphatase substrates are used in ELISA assays to detect alkaline phosphatase-conjugated molecules via a colorimetric enzymatic reaction. pNPP 1-Component AP Microwell Substrate with Stabilizing Pellets contains para-Nitrophenylphosphate (pNPP). This formulation of pNPP substrate also contains a stabilizer to extend the shelf life of the alkaline phosphatase substrate on your benchtop to 2-3 days.
The alkaline phosphatase substrate reaction may be stopped with the use of a stop solution, Stop Solution for pNPP AP Microwell Substrates (STOPP).
Bulk volumes are available upon request.
