Phosphatase Inhibitor Cocktail (EDTA free) (100X)

EDTA free

Phosphatase Inhibitor Cocktail is a mixture of several inhibitors to protect valuable proteins from dephosphorylation. The product preserves phosphorylated proteins existing in small quantity in cells and tissues. This product does not interfere with metalloproteins since it is EDTA free.

  • Contains 6 kinds of phosphatase inhibitors for different targets.
  • 100 times concentrated stock solution. Dilute with any buffer of your choice.
  • Stable for two years in refrigerator (2-8 °C).
  • Ready to use.

  • If phosphatase concentration is high, it can be diluted by 20-50 fold.
  • The product may cause inhibition of 2D electrophoresis. Remove inhibitors by dialysis or desalt before use.
  • The product does not contain protease inhibitors. For homogenizing cells and tissues, if necessary, add protease inhibitor cocktail, such as Protease Inhibitor Cocktail (EDTA free) (Cat. No.: 03969).
  • The product includes Imidazole for inhibitor. In case of Metal Affinity Purification, it is recommended a pretest with reducing Imidazole concentration in the buffer by 5 mM.
  • The product colors gradually.
  • Direct light may interfere with an inhibition effect; shield the product from the light after using.
  • The components may be precipitated during storage. Before use, melt it by vortex at 30-40°C shielding light.
