The Halt Phosphatase Inhibitor Cocktail protects phosphoproteins from serine/threonine phosphatases as well as protein tyrosine phosphatases (PTPs). The cocktail contains a mixture of four inhibitors of broad specificity, including sodium fluoride, sodium orthovanadate, sodium pyrophosphate, and β-glycerophosphate. Conveniently packaged in a 100X format, the cocktail is stable at 4°C and is suitable for use with any cell or tissue extract. The cocktail preserves protein phosphorylation in immunoprecipitation and kinase assays. Furthermore, the cocktail is compatible with popular protein assays such as the Thermo Scientific Pierce™ BCA Protein Assay Kit (Part No. 23225) and Bradford-based Pierce Coomassie Plus™ Assay Kit (Part No. 23236).


  • All-in-one format inhibits both serine-threonine phosphatases and protein tyrosine phosphatases

  • Compatible works with standard protein assays, including BCA and coomassie (Bradford) assays

  • Convenient storage refrigerator (2 to 8°C) storage saves valuable space in the freezer and provides for immediate use

  • Multiple sizes select a package size of the 100X cocktail that is ideal for any particular scale and workflow of protein extraction experiment
