Sodium Orthovanadate is a commonly used general inhibitor for protein tyrosine phosphatases (PTPs), alkaline phosphatase (ALP) and ATPase. Sodium Orthovanadate acts as a competitive inhibitor and is completely reversible upon the addition of EDTA or by dilution. The PTP activities of Sodium Orthovanadate are conveniently separable from the protein phosphoseryl and phosphothreonyl phosphatase (PSP) activities inhibited by Fluoride and EDTA. Sodium Orthovanadate is routinely used to preserve the protein tyrosyl phosphorylation state in cells, cell lysates, and protein tyrosine kinase assays.

사용법 :
Sodium orthovanadate stock solutions (1 mM or higher, as desired) may be prepared in water with the pH adjusted to pH ~10. To ensure the presence of vanadate monomers, boil the solution until translucent and readjust the pH to 10. The precise concentration of a dilute aqueous solution (pH 10.5) may be determined using the molar extinction coefficient (eM= 3,550 at 260 nm). Orange color observed before boiling is due to decavanadate. At pH 10, decavanadate will slowly depolymerize over several hours to the colorless monovanadate; however, the process is accelerated by boiling.
