The Phos-tag™ Mass Analytical Kit can be used to provide a simple, rapid, and sensitive matrix-assisted laser desorption/ionisation-time of flight mass spectrometry (MALDI-TOF MS) analysis of phosphorylated compounds.

Phosphorylated molecule-Phos-tag™ complex is detected in a positive mode, and phosphorylated molecules usually difficult to detect can be detected with improved sensitivity.
