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.

Overview

• Rapid and simple procedure to generate digested peptides
• Simultaneous digestion, purification and concentration at once
• Peptide generation is complete, with no generation of additional artifacts being detected in mass spectrometry
• Peptides are ready for applications such as mass spectrometry and SDS-PAGE
• Purification is based on spin column chromatography that uses Norgen’s resin separation matrix

This kit is highly efficient in the enzymatic digestion of simple and complex protein samples using trypsin and the subsequent purification of the resulting peptides using a convenient spin column format.  Trypsin is added to the protein sample and bound to the column.  Salts are washed away and the trypsin is then activated to digest proteins.  Peptides are then eluted in a small volume and ready for downstream analysis. The peptides generated are complete, with no additional artifacts being detected in mass spectrometry.  Fifteen micrograms of protein can be processed, digested and purified with each spin column with about 20 minutes of hands-on time (plus trypsin incubation).   The simultaneous protein digestion and volumetric concentration of the purified peptides makes the kit a convenient method for preparing peptides to be analyzed by many downstream applications such as mass spectrometry and more.
