PEG3-(Amino-Tri-(Propargyl-PEG2-ethoxymethyl)-methane)-(Amino-Tri-(endo-BCN-PEG2-ethoxymethyl)-methane) is reactive with azide-bearing compounds or biomolecules via copper catalyzed azide-alkyne Click Chemistry to yield a stable triazole linkage. The DBCO groups are commonly used for copper-free Click Chemistry reactions due to their strain promoted high energy. The hydrophilic PEG chain allows for increased water solubility.

The Phosphate Assay Kit is a rapid, simple, reliable and accurate method for the specific measurement and analysis of phosphate in water, 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.
This method is suitable for analysis using spectrophotometer and auto-analyser.
Note for Content: The number of manual tests per kit can be doubled if all volumes are halved.
