PhosphoSafe Extraction Buffer efficiently extracts cytosolic proteins from mammalian and insect cells while preserving their phosphorylation state. This reagent contains the same formula as CytoBuster Protein Extraction Reagent (Trim 2001), but also includes four phosphatase inhibitors: sodium fluoride, sodium vanadate, β-glycerophosphate, and sodium pyrophosphate. PhosphoSafe Extraction Reagent is compatible with kinase assays, protein interaction analysis, and other applications. This reagent is provided in convenient 25-ml bottles (1 bottle for 71296-3, 5 bottles for 71296-4).
