Ürün bilgileri "p-Nitrophenylphosphate (5mg) tablets"

24 respective 100 ready-to-use para-Nitrophenylphosphate (pNPP) tablets with 5mg p-Nitrophenylphosphate. Each tablet dissolved in 5mL deionized water yields a solution containing 1.0mg/mL pNPP, 0.2M Tris buffer.

Genaxxon's pNPP substrate is specifically developed for immunoassay procedures and it is ideal for phosphate-based ELISA methods. The substrate is also used as a chromogenic non-specific substrate in alkaline and acid phosphatase assays. Its soluble end-product is yellow and can be spectrophotometrically read at 405 to 410 nm. The reaction may be stopped with 3M NaOH.

The pNPP substrate is supplied as pre-weighed tablets in bottles or in convenient blister packs, each tablet containing 5mg or 20mg of substrate.

How to use:
Deposit one tablet of the pNPP substrate in a laboratory flask or beaker placed on a magnetic stirrer. Add deionized water in the appropriate amount to reach the required concentration for the assay. Stir until full dissolution and the substrate solution is ready to use.

One tablet dissolved in 5mL of substrate buffer results in a 1mg/mL solution.
