Tobacco Etch Virus nuclear-inclusion-a endopeptidase or TEV is highly sequence specific cysteine protease. It has a strict 7 amino acid cleavage recognition sequence of Glu-Asn-Leu-Tyr-Phe-Gln ↓ (Gly/Ser). The high specificity makes this protease excellent for the removal of affinity-tags from purified recombinant proteins. Purified TEV was expressed in E.coli and is shipped in 4°C packaging to preserve activity. TEV cleavage is best performed at room temperature in a P.H range of 4 – 9. Protease is an improved version of Tobacco Etch Virus (TEV) protease that is highly site-specific, highly active, and significantly more stable than native TEV protease, resulting in enhanced long-term activity.
