Amid Biosciences' 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°C; however, it can be used at temperature as low as 4°C. 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.
Features and Benefits:
- Highly specific cleavage activity
- Enhanced enzyme stability for prolonged protease activity
- Activity over a broad temperature (+4°C to 30°C) and pH (6.0 to 8.5) range
- His tag to facilitate its removal from the digested protein samples
