product name

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

Quality Level

200

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.

Nucleotide pyrophosphatase/phosphodiesterase-1 (NPP1) inhibitors have been suggested as a potential treatment for calcium pyrophosphate dihydrate (CPPD) deposition disease. Here, we targeted the development of improved NPP1 inhibitors based on acyclic mimics of Pα,α-phosphorodithioate-substituted adenine nucleotides, 7-10. The latter were obtained

Calcium pyrophosphate deposition (CPPD) is associated with osteoarthritis and is the cause of a common inflammatory articular disease. Ecto-nucleotide pyrophosphatase/phosphodiesterase 1 (eNPP1) is the major ecto-pyrophosphatase in chondrocytes and cartilage-derived matrix vesicles (MVs). Thus, eNPP1 is a principle contributor to

Colorimetric Alkaline Phosphatase and Peroxidase Substrate Detection Systems

Nitroblue Tetrazolium (NBT) is used with the alkaline phosphatase substrate 5-Bromo- 4-Chloro-3-Indolyl Phosphate (BCIP) in western blotting and immunohistological staining procedures. These substrate systems produce an insoluble NBT diformazan end product that is blue to purple in color and can be observed visually.
