AnaSpec has announced the recent release of the SensoLyte® 520 TEV Protease Assay Kit. This kit uses a 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.

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.
