Recombinant Tobacco Etch Virus Protease produced in E.coli I has a molecular mass of approximately 27 kDa.
>95% by SDS-PAGE and HPLC analyses.
Store rTEV at -70°C for long term or at -20°C for < 6 months.
Recombinant TEV Protease(rTEV) is a site-specific protease purified from E. coli. The protease can be used for the removal of affinity tags from fusion proteins. The seven-amino-acid recognition site for rTEV is Glu-Asn-Leu-Tyr-Phe-Gln-Gly with cleavage occurring between Gln and Gly. The optimal temperature for cleavage is 30°C; however, the enzyme can be used at temperatures as low as 4°C. rTEV contains both GST and His tag, and can be easily removed from the digestion reaction by affinity chromatography.
