Phosphorylated substances and stabilizing phosphorylated compounds were previously difficult to measure due to chemical instability.

Now they can be readily detected using the Phos-tag™ acrylamide, agarose, biotin and MS kit available exclusively in the UK from Alpha Laboratories.

Protein phosphorylation has a prominent role in signal transduction and the versatile Phos-tag has been adapted to create a number of tools for phosphorylation analysis.

This novel Phos-tag labelling system was developed by the Department of Functional Molecular Science at Hiroshima University and recognizes the phosphate monoester group.

Under neutral physiological pH conditions Phos-tag strongly binds phosphomonoester di-anions enabling it to replace conventional enzyme immunoassay and radioactive isotope methods for capturing substances with a phosphate monoester group.

Post-translational modification by phosphorylation plays a vital role in regulating the function, activity and location of numerous protein targets.

Phos-tag labelled acrylamide is available for electrophoresis applications like SDS-PAGE mobility shift assays and Phos-tag biotin can be used in Western Blot detection in place of an anti-phospho antibody.

Adaptation of the Phos-tag for use in column chromatography, by construction of a column with labelled agarose, enables purification based on phosphate affinity, providing enriched fractions for further phosphoproteomic investigations.

Phos-tag can even provide a radiation free solution for MALDI-TOF/MS analysis.
