Overview
 
Sodium Orthovanadate (Part ACTVO-4) is provided as a potent phosphatase inhibitor that has been pre-activated and depolymerized by pH10 adjustment and boiling cycles until the solution maintains a colorless appearance at equilibrium at pH10§.  This preparation depolymerizes sodium orthovanadate and enhances its phosphotyrosyl phosphatase inhibitor potency.§  

Activated sodium orthovanadate solution is ready-to-use and can be dispensed directly into cell lysates, or cell culture medium (after filter sterilization if applied over an extended duration;  i.e. overnight.  Sterilization for cell culture applications is not required for short duration exposure;  i.e < 5 hrs). 
 
Pre-activated sodium orthovanadate solution is stable for at least one year when stored at -20oC as provided.  Certain buffer components, such as EDTA and oxidants, interact with inhibition potency.  HEPES is a preferred buffer for cell lysis solutions to maintain vanadate potency.2

Sodium Orthovanadate (Vanadate) Applications:

  1. Maintains tyrosyl phosphorylation in cell lysates and live cell culture (syringe filter sterilization is required for cell culture).
  2. Alkaline phosphatase inhibitor
  3. ATPase inhibitor, including ABC transporters
  4. Use as a stock solution for pervanadate generation


  Directions (Phosphatase Inhibition)                                                                                                                               
  1. Concentration:  Recommended experimental sodium orthovanadate (vanadate) concentration for phosphatase inhibition is 1 mM. 
  2. Cell lysates:  Dispense the 200 mM stock sodium orthovanadate solution directly into cell lysates to make a final concentration of 1 mM. 
  3. Cell culture:  Syringe sterilize with a 2 micron filter, dispense the 200 mM stock solution to cell culture medium to make a final 1 mM concentration.
