SelecTEV™ Protease is a 27 kD improved form of Tobacco Etch Virus (TEV) protease that has been engineered to be more stable, active, and specific than the native protease. SelecTEV™ Protease is a cysteine protease that recognizes the TEV recognition sequence Glu-Asn-Leu-Tyr-Phe-Gln-Gly and cleaves between Gln and Gly. This seven-amino-acid sequence is rarely found in proteins, making SelecTEV™ Protease an ideal choice for tag removal of fusion proteins. The optimal temperature for cleavage is 30°C, however the enzyme is active over a wide temperature range (4 – 30°C) and pH (6.0 – 8.5) to accommodate your specific protein. Following digestion, SelecTEV™ Protease is easily removed from the cleavage reaction by affinity chromatography using the polyhistidine tag at the N-terminus of the protease. SelecTEV™ Protease is purified from E. coli by affinity chromatography using the polyhistidine tag and is 90% pure when visualized on an SDS-PAGE gel.

SelecTEV Protease can be used with the Expresso Solubility and Expression Screening System vectors, which contain a TEV cleavage recognition site.


SelecTEV™蛋白酶是一种27 kD改良形式的**蚀纹病毒(TEV)蛋白酶,经过设计,比天然蛋白酶更稳定,更有活性和特异性。SelecTEV™蛋白酶是半胱氨酸蛋白酶,其识别TEV识别序列Glu-Asn-Leu-Tyr-Phe-Gln-Gly并在Gln和Gly之间切割。这种七氨基酸序列很少见于蛋白质,使SelecTEV™蛋白酶成为融合蛋白标签去除的理想选择。zui佳裂解温度为30°C,但酶在较宽的温度范围(4 - 30°C)和pH(6.0 - 8.5)范围内具有活性,可以适应您的特定蛋白质。消化后,使用蛋白酶N-末端的多组氨酸标签通过亲和层析容易地从切割反应中除去SelecTEV TM蛋白酶。SelecTEV™蛋白酶经过纯化  使用多组氨酸标签通过亲和层析进行大肠杆菌,并且在SDS-PAGE凝胶上观察时纯度为90%。

SelecTEV蛋白酶可与Expresso溶解度和表达筛选系统载体一起使用,其含有TEV切割识别位点。
