Phosphatase Inhibitor Cocktail III (2 Tubes, 100x)

Catalog No. C0004

It is easy for the proteins to be degraded or dephosphorylated during in vitro extraction procedure, which could cause an inaccurate result of protein expression detection. Therefore, adding protease inhibitors or phosphatase inhibitors into the extracts would be an effective method to prevent degradation and dephosphorylation of protein.

The phosphatase inhibitor mixture can effectively inhibit the dephosphorylation of common phosphatases on proteins and maintain the original phosphorylation state of proteins.

  • Accurate Ingredients —— Clearance of components and concentrations to avoid experimental uncertainty
  • Comprehensive Protection—— Effectively inhibit various proteases to protect proteins from being degraded
  • Cost-Effective —— Lower price with higher quality

Handling Instruction

  • Compatible with Western Blot analysis, IP, Co-IP, pull-down, IF, IHC, kinase assay and etc.
  • Add concentrated cocktail at 1:100 (v/v) dilution to samples solution (such as cell lysates or tissue extracts) before assaying.
  • Briefly vortex cocktails to help facilitate the dissolution.
  • Note to add tube I first, mix well, then add tube II, mix again.


  • Following initial thaw, aliquot and freeze (-20°C) to avoid thawing and refreezing repeatedly.
  • If Cocktail I and Cocktail II are used together, do not mix tube I with tube II beforehand, as there may be precipitation. To avoid this, please add them step by step during experiment.
