商品介绍
rTEV 蛋白酶(重组型)是经过基因工程改造后的重组蛋白酶,该酶特异性识Glu-Asn-Leu-Tyr-Phe- Gln-Gly 七氨基酸序列。rTEV 蛋白酶与肠激酶 U(EK)、Thrombin、FactorXa、SUMO 等蛋白酶相比,具有高活性、高特异性的双重特点,rTEV 蛋白酶因具高剪切活性和特异性,已成为融合蛋白表达后去除融合 tag 的首选蛋白酶。该酶经 6×His 标签纯化而得(含组胺酸标签),纯度达99%, 剪切反应完毕后可通过His标签纯化树脂Ni-NTA Resin(Cat.No. P2010)去除,以达到纯化目的蛋白的目的。表1.不同温度下rTEV酶切活性反应时间不同温度下剪切活性(%)4°C16°C21°C30°C1 h345856702 h588078903 h719999993.5h84999999影响天然TEV酶活性的常见因素:1)PMSF和AEBSF(1 mM),TLCK(1 mM),Bestatin(1 mg/ml)、Pestatin A(1 mM),EDTA(1 mM)以及E-64(3 mg/ml),以上这些蛋白酶抑制剂对rTEV的活性没有影响;2)Zn离子(>5 mM)对rTEV活性有抑制;3)与半胱氨酸反应的试剂也是rTEV的潜在抑制剂。表达方式: A DNA sequence encoding the TEV Protease (NP_062908) (Gly 2038- Gly 2280) was fused with polyhistidine tag at the N-terminus, with a Ser 2256 Asn mutation种属:Human表达宿主: E.ColiQC Testing纯度:> 95%, as determined by SDS-PAGE内毒素:< ﹤1.0 EU per 1μg cytokine as determined by the LAL method.稳定性:Samples are stable for up to twelve months from date of receipt -70°C预测N端: Met 1分子量:The recombinant human TEV protease consists of 251 amino acids and has a predicted molecular mass of 28.6 kDa. As estimated in SDS-PAGE under reducing conditions.缓冲液: Supplied as a 0.2μm filtered solution of 50mM Tris, 10%Sucrose,5mM DTT pH8.0SDS-PAGE:Usage Guide储存方法:Store it under sterile conditions at -70℃. It is recommended that the protein be aliquoted for optimal storage and usage. Avoid repeated freeze-thaw cycles.备注:产品信息可能会有优化升级。请以实际标签信息为准。备注:以上数据均来自公开文献, Solarbio暂未进行独立验证, 仅供参考。These protocols are for reference only. Solarbio does not independently validate these tmethods.
