Achieve immediate, effective, and convenient inhibition of a broad spectrum of phosphatases across a wide range of sample materials (e.g., mammalian, plant, yeast, and bacteria) with non-toxic PhosSTOP Phosphatase Inhibitor Cocktail Tablets. PhosSTOP is a proprietary blend of phosphatase inhibitors, formulated as a ready-to-use, quick-dissolving, water-soluble tablet.

  • Comprehensive protection: Inhibit acid and alkaline phosphatases, as well as serine/threonine (PP1, PP2A, and PP2B) and tyrosine protein phosphatases (see Figure 1).
  • Safe: Dissolve the non-toxic PhosSTOP Tablets in aqueous solutions and avoid organic solvents (e.g., DMSO).
  • Suitable for formalin fixation: Maintain phosphorylation status of proteins in histological sections (see Figure 2).
  • Convenient: Eliminate the time-consuming search for just the right phosphatase inhibitor.
  • Easy to use: Simply drop a quick-dissolving tablet into your buffer.
  • Stable: Store stock solutions for 1 month at +2 to +8°C, or for at least 6 months at -15 to -25°C. 

For all-inclusive protein protection, combine PhosSTOP with cOmplete or cOmplete ULTRA Protease Inhibitor Tablets to inhibit both phosphatases and proteases


Each PhosSTOP Tablet contains a proprietary blend of phosphatase inhibitors.
