Megazyme Phosphate Assay Kit

SKU: K-PHOS

The Phosphate Assay Kit is a rapid, simple, reliable and accurate method for the specific measurement and analysis of phosphate in foodstuffs, beverages and other materials. The phosphate detection reaction employs the defined chemical substrate 2-amino-6-mercapto-7-methylpurine ribonucleoside (MESG). In the presence of phosphate, the substrate is converted enzymatically by purine nucleoside phosphorylase (PNPase) to the products ribose 1-phosphate and 2-amino-6-mercapto-7-methylpurine. An application note describes the dephosphorylation reaction of phytic acid using phytase and alkaline phosphatase (sold separately), and subsequent phosphate detection using the reagents provided in K-PHOS.

Note for Content: The number of manual tests per kit can be doubled if all volumes are halved.
