Active Recombinant TEV Protease, His-tagged

• Cat.No.: Protease-23T
• Product Overview: Recombinant TEV protease contains an N-terminal His tag and can be easily removed by immobilized metal affinity chromatography (IMAC) from the cleavage reaction. The enzyme is compatible for both in-solution and on-column cleavage reactions. TEV Protease is purified from E. coli by proprietary chromatographic techniques and is >90% pure when visualized on an SDS-PAGE gel.

Specification

• Description: TEV Protease is a 27 kDa engineered form of Tobacco Etch Virus (TEV) protease. The optimum recognition site for TEV protease is the seven-amino-acid sequence Glu-Asn-Leu-Tyr-Phe-Gln-(Gly/Ser) [ENLYFQ(G/S)] with cleavage occurring between the Gln and Gly/Ser residues. The enzyme is highly specific and active for its seven-amino acid sequence with minimal off-target effects which makes it an ideal choice to remove affinity tags from fusion proteins after protein purification. The optimal temperature for cleavage is 30 centigrade; however, it can be used at temperature as low as 4 centigrade.
