How do you make sodium orthovanadate stock solution?
To prepare a 50-ml stock solution of 0.1 M sodium orthovanadate, add 0.92 g of powder (Sigma, St. Louis, MO) to 30 ml of H2O, and adjust to pH 10 with HCl. The solution should turn yellow. Boil the solution until it is colorless, and recheck the pH.
What is the chemical formula of sodium vanadate?
Na3VO4
Sodium orthovanadate/Formula
How do you make a na3vo4 solution?
Prepare a stock solution of 200 mm sodium orthovanadate (Na3VO4). Adjust the pH of the 200 mm stock solution to 10 using 1 n NaOH or 1 n HCl. (At a pH of 10 the solution should be yellow.) Boil until the solution clears (~10 min).
What is sodium orthovanadate?
Sodium Orthovanadate (Vanadate, Na3VO4) is a commonly used general inhibitor for protein phosphotyrosyl phosphatases (PTPs). It is a competitive inhibitor. The inhibition by Vanadate is completely reversible upon the addition of EDTA or by dilution.
How do you make 200mm sodium orthovanadate?
1) Prepare a solution of 200 mM sodium orthovanadate in ultrapure dH20 according to protocol by Gordon (1991) PubMed. For a 100 mL solution, add 3.68 g Na3VO4 to 90 mL water and dissolve with stirring. Once dissolved, bring volume to 100 mL.
What does NAF do in lysis buffer?
Sodium fluoride, as well as Sodium PyroPhosphate and Sodium Ortovanadate, is usually added in protein lysis buffers (such as RIPA, JS or E1A) to inactivate endogenous phosphatases and protect protein phosphorylations.
Is na3vo4 a color?

Is Vanadium a metal?
vanadium (V), chemical element, silvery white soft metal of Group 5 (Vb) of the periodic table. It is alloyed with steel and iron for high-speed tool steel, high-strength low-alloy steel, and wear-resistant cast iron.
What are phosphatase inhibitors?
Product Description. This Phosphatase Inhibitor Cocktail is used to prevent dephosphorylation of phosphorylated proteins from active serine/threonine and tyrosine phosphatases present in whole cell extract. The 100X cocktail is a colorless to light yellow liquid.
Why does NaF stop glycolysis?
NaF inhibits enolase, an enzyme acting late in the glycolytic pathway, and has no effect on enzymes that act early in the glycolytic pathway. Glycolysis is instantly inhibited in erythrocytes, leukocytes and platelets when the blood pH is maintained between 5.3 and 5.9 with a citrate buffer.
Which of the following is the importance and uses of sodium fluoride NaF?
Uses: Sodium fluoride is widely used as a fluorinating agent in toothpastes and water supplies to maintain dental health. Another important application is in nuclear medical imaging, where radioactive sodium fluoride (NaF18) is used as a radiotracer for detecting various conditions.
How is sodium orthovanadate ( vanadate ) reversible in the presence of EDTA?
Vanadate has been fully activated. Sodium Orthovanadate (Vanadate) is a general competitive inhibitor for protein phosphotyrosyl phosphatases. The inhibition by Sodium Orthovanadate is reversible upon the addition of EDTA or by dilution.
How to make sodium orthovanadate with distilled water?
1.839 g Sodium orthovanadate 8ml distilled water to 8 ml Add 1.839 g Sodium orthovanadate to a screw cap tube (falcon) Make up to 8ml with distilled water. If solution is yellow, place in boiling water until clear. Re-check pH and repeat as necessary.
How to make 100 mM EDTA stock solution?

Is there a 10% sodium deoxycholate stock solution?
The 10% sodium deoxycholate stock solution (5 g into 50 ml) must be protected from light. The 100 mM EDTA stock solution is made with 1.86 g into 40 ml H 2O and then add NaOH to dissolve and adjust pH to 7.4. Finally, adjust the total volume to 50 ml). Store the buffer at 4°C.
