Description

& Advantages

Phosphorylation of proteins and lipids is a hallmark of the signaling or metabolic status of cells. A cocktail of three inhibitors that will inhibit alkaline phosphatases as well as serine/threonine protein phosphatases such as PP1 and PP2A. Each vial contains 1 ml phosphatase inhibitor cocktail solubilized in DMSO with the following components: Bromotetramisole oxalate (2.5 mM), Cantharidin (500 µM), and Microcystin-LR , Microcystis aeruginosa (500 nM).

Phosphatase Inhibitor Cocktail I has been optimized and tested for mammalian cell and tissue extracts. This cocktail is supplied as a ready-to-use solution in DMSO.

The product should be stored at -20°C, and is stable for up to 12 months. When kept at 2-8°C, the product remains stable for 2 months.

Thaw at room temperature. Before assaying, add each solution at 1:100 (v/v) dilution to samples (such as cell lysates or tissue extracts). Mix the sample sufficiently after each time of addition.

Application Fields: Western Blot analysis, Co-IP, pull-down, IF, IHC, kinase assay and etc.
