The Phosphatase Inhibitor Cocktail (100X) is composed of a proprietary mix of sodium fluoride, sodium pyrophosphate, β-glycerophosphate, and sodium orthovanadate to promote broad spectrum protection against endogenous serine/threonine and tyrosine phosphatases.

*This blog is created based on the frequent question about Phosphatase Inhibitor Cocktail III(P-1549) application from our customers.

Q. How much volume of stock solution will be added to a certain amount of cell lysate?
A. 1mL of the stock solution is good for 500 mg of protein extracted from the tissue or cells. Here is the Recommended Usage. Recommended for use with tissue and cell extracts including extracts containing detergents. Reconstitute each vial with 1 ml H2O to obtain a 1 ml stock solution

Q. How about 800uL lysis buffer to lysate 10x10 cm2 cell?
A. With an unkown amount of protein his is hard to be exact with a recommendation. It is essential to use too much then to use too little phosphatase inhibitor. Description: When diluted in lysis buffer to a final concentration of 1X the 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.

Directions for Use:

1. Briefly vortex the Phosphatase Inhibitor Cocktail (100X) before use. 2. Just prior to lysing cells, dilute the cocktail 1:100 in desired lysis buffer to obtain a 1X working concentration 3. Solutions and Reagent: The Phosphatase Inhibitor Cocktail (100X) is composed of a proprietary mix of sodium fluoride, sodium pyrophosphate, β-glycerophosphate, and sodium orthovanadate to promote broad spectrum protection against endogenous serine/threonine and tyrosine phosphatases. 4. Background: Dynamic protein phosphorylation is a key cellular signaling mechanism by which a broad spectrum of cellular processes is regulated. In order to study the phosphorylation status of specific target proteins the phosphorylated residue of interest must remain intact. When cells are lysed to make whole cell extracts, a loss of normal cellular signaling regulation occurs, and phosphatases within the cell extract are free to dephosphorylate proteins in an uncontrolled manner. The addition of phosphatase inhibitors to the cell lysis buffer aids in the preservation of phosphorylated residues at the time of cell disruption. 5. After reviewing some other papers use of 1 vial, prepared as stated above, inhibits> 96% of the phosphatases. We would offer this as researchers starting point.
