The Xpert Phosphatase Inhibitor Cocktail Solution(100X)

is a mixture of several inhibitors to prevent valuable 

proteins from dephospholylation. Phosphorylation and 

dephosphorylation is a molecular on/off switch that regulates 

a number of key biological pathways within the cell, 

including signal transduction, cell division, and apoptosis.

The Xpert Phosphatase Inhibitor Cocktail preserves 

phosphorylation of proteins in cell lysates and tissue

extracts. The cocktail contains a mixture of four 

phosphatase inhibitors of broad specificity, including 

sodium fluoride, sodium orthovanadate, sodium 

pyrophosphate and sodium glycerophosphate. 

Unlike other commercially available phosphatase

inhibitor cocktails which protect against either 

Ser/Thr phosphatases or protein tyrosine 

phosphatases.

The Xpert 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 the BCA Protein Assay and Bradford-

based assays such as Coomassie.
