product name

Alkaline Phosphatase Yellow (pNPP) Liquid Substrate System for ELISA, ready to use solution

Quality Level

form

liquid

storage temp.

2-8°C

General description

The product is ready to use buffered alkaline phosphatase substrate consist of p-nitrophenylphosphate (pNPP). This is the advanced substrate system contains insoluble stabilizer that enhances the stability and reactivity as well as reduces the base-line absorption. It produces a soluble end product, hence not recommended for blotting or histochemistry applications.

Application

Develops a soluble yellow reaction product that may be read at 405 nm. For endpoint assays, the reaction may be stopped with 3 N NaOH. Recommended for ELISA (microwell) procedures; not recommended for membrane applications.

Caution

 Stable at least one year at 2-8 °C.

Physical form

Ready to use

Preparation Note

Contains p-nitrophenyl phosphate, a substrate for alkaline phosphatase.
