Cell Culture Supplements and Additives

Thermo Scientific Halt Phosphatase Inhibitor Cocktail preserves the phosphorylation state of proteins during and after cell lysis or tissue protein extraction.


  • All in one format - Halt Phosphatase Inhibitor Cocktail inhibits both serine/threonine as well as protein tyrosine phosphatases
  • Compatible with standard protein assays
  • User friendly storage at 2 to 8 °C - Halt Phosphatase Inhibitor Cocktail does not require frozen storage
  • Convenient size - 1 mL of cocktail protects up to 100 mL of sample


The cocktail contains a mixture of four phosphatase inhibitors of broad specificity, including sodium fluoride, sodium orthovanadate, sodium pyrophosphate and -glycerophosphate. Unlike other commercially available phosphatase inhibitor cocktails, which protect against either serine/threonine phosphatases or protein tyrosine phosphatases, the Halt Phosphatase Inhibitor Cocktail protects phosphoproteins from both families of phosphatases. Conveniently packaged in a 100X format, the cocktail is stable at 4 °C and is compatible with common protein assays, including Bradford-based assays.
