Propargyl-PEG4-Ms has an alkyne group and a mesylate group. The mesylate group is a sulfonate ester for nucleophilic substitution reactions (SN2). The alkyne group can react with azides via copper catalyzed Click Chemistry reactions. The PEG units help increase the solubility of the molecule in aqueous environments. Reagent grade, for research use only.

Reaction Time (min):
~ 20 min
Application examples:
Processed foods and drinks, bakery products, dairy products, waste water samples, cosmetics, pharmaceuticals and other materials (e.g. biological cultures, etc.).
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.
