Tobacco Etch Virus (TEV)

Dry Ice

Tobacco Etch Virus (TEV) proteinase is widely used to remove fusion tags from recombinant proteins. It recognizes specific sequence Glu-Asn-Leu-Tyr-Phe-Gln-Gly and cleaves between Glutamine and Glycine residues. TEV protease is active even at 4 C, making it the protease of choice for fusion proteins or tags removal. The SensoLyte TEV Protease Assay Kit uses TEV specific Glu-Asn-Leu-Tyr-Phe-Gln-Gly substrate labeled with 5-FAM dye and QXL 520 quencher. Proteolytic cleavage of this quenched 5-FAM-QXL 520 conjugate yields a brightly green fluorescence, which can be continuously monitored at Ex/Em= 490/520 nm. Increase in fluorescence intensity is directly proportional to the TEV protease quantity/activity.
