General description

Phosphatase Inhibitor Cocktail 2 is a mixture of components designed to inhibit enzymes that modify proteins present in cell extracts, leading to improved yields of intact proteins. It has been optimized and tested for use on various animal tissues and cytosolic extracts.

Application

The phosphatase inhibitor cocktail improves the yields of intact proteins by adding inhibitors to enzymes that modify proteins present in cell extracts. This product has been optimized and tested for tyrosine protein phosphatases, acid and alkaline phosphatases. It has been tested on cell extracts from animal tissues including bovine liver and human placenta, and cytosolic extract of rabbit muscle.

Biochem/physiol Actions

This mixture contains individual components with specific inhibitory properties. Sodium orthovanadate inhibits a number of ATPases, protein tyrosine phosphatases, and other phosphate-transferring enzymes. Sodium molybdate inhibits acid and phosphoprotein phosphatases. Sodium tartrate inhibits acid phosphatases. Imidazole inhibits alkaline phosphatases.

Features and Benefits

This compound is a featured product for Kinase Phosphatase Biology research. Click here to discover more featured Kinase Phosphatase Biology products. Learn more about bioactive small molecules for other areas of research at sigma.com/discover-bsm.

Caution

As supplied, this product is stable for two years at the recommended 2-8°C storage temperature.

Preparation Note

This cocktail is supplied as a clear aqueous solution. It has been sterile filtered through a 0.2 μm membrane in bottles that have been aseptically filled. One mL will inhibit phosphatase activities found in the 100,000 x g supernatant from human placenta, bovine liver, rabbit muscle, A431, or Jurkat cell extracts at a protein concentration of approximately 5 mg/mL.
