Phos-tag™ Agarose

Phos-tag™ Agarose is used to enrich, separate, and purify phosphorylated proteins using column chromatography. One of their main properties being free of reductants or surfactants, it can refine phosphorylated proteins in their native shape.


  • Phosphorylated proteins can be purified within 1 hour
  • The proteins can be trapped in physiological condition (pH 7.5)
  • Purified without reducing agent and surfactant

Purified proteins can be used in processes such as mass spectrometry, Western blotting, or SDS-PAGE electrophoresis.

Timesaving, ready-to-use Phos-tag agarose tip is also available to purify phosphorylated peptides.
