Soluble AP Substrates
In a soluble chromogenic Alkaline Phosphatase (AP) assay setup, like an ELISA, the preferred substrate is pNPP (p-nitrophenylphosphate). Kementec offers two different pNPP solutions, which are mono-component and stable for up to 36 months.
pNPP liquid ready-to-use substrate is highly active. The substrate gives superior results due to its sensitivity, allowing very low detection limits.
pNPP ONE liquid ready-to-use substrate is incredibly stable. PNPP ONE shows superior background characteristics due to its high temperature robustness.
Both pNPPs are ECO-TEK, making them REACH, Annex XVII compliant and easy to transport with less restrictions. ECO-TEK includes:
- Free of Toxic Preservatives
- Free of Harmful Organic Solvents
- Free of Hazardous Stop Solutions
