Product Description

TCEP (Tris (2-Carboxyethyl) phosphine Hydrochloride) is an odorless reducing agent suitable for protein applications and in the preparation for electrophoresis. TCEP is water soluble, is stable in a variety of solutions and is particularly useful in the labeling of cysteine residues with maleimides, preventing the cysteines from forming disulfide bonds. As a reducing agent, TCEP has many other desirable features, including:

• TCEP-HCl is stable in air.
• TCEP-HCl is odorless so reactions can be carried out on the bench without the need for a fume hood.
• TCEP-HCl is efficient and can be used to reduce disulfide bonds at low concentrations.
• TCEP-HCl is selective for disulfides and does not react with other protein side chains.
• TCEP-HCl may be used as a substitute for DTT at a final concentration of 50mM.
