Description

General description

A cocktail of four phosphatase inhibitors for the inhibition of both serine/threonine and protein tyrosine phosphatases. Available as 1 ml or as a set of five 1 ml vials.

Application

Phosphatase Inhibitor Cocktail Set V, 50X has been used:

• as a supplement in the lysis buffer to dissociate metabolically activated one (MMe) bone marrow macrophages (BMDMs) for Western blot
• in radio-immunoprecipitation assay (RIPA) modified buffer to incubate cultured human umbilical vein endothelial cells (HUVECs) for western blot
• in lysis buffer to lyse cultured HUVECs for immunoprecipitation
• in wash buffer to wash the protein complexes
• as a component in 4-(2-hydroxyethyl) piperazine-1-ethanesulfonic acid (HEPES) buffer to homogenize J774 cells to assess the effect of lipopolysaccharides (LPS) incubation on cytosolic phospholipase A2 (cPLA2) activity

Biochem/physiol Actions

Protein phosphorylation and dephosphorylation play a crucial role in signal transduction, controlling various cellular processes such as cell division, proliferation, and apoptosis. Protein kinases add a phosphate group to specific serine, threonine, or tyrosine residues, which alters the protein′s conformation and its ability to interact with ligands. Protein phosphatases then remove the phosphate group, restoring the protein to its original dephosphorylated state. When extracting phosphorylated proteins from cell and tissue lysates, it is of utmost importance to preserve their phosphorylation state.

Features and Benefits

• Convenient: formulations are ready-to-use, making them easy to use.
• Consistent: high-quality formulations ensure reliable and reproducible performance.
• Flexible: the cocktails are designed to target different categories of phosphatases, offering versatility in experimentation.
