Product overview
TEV Protease Activity Assay Kit (Flurometric) (ab211109) provides a convenient method for detecting TEV (Tobacco Etch Virus) Protease activity in cell lysates from infected individuals, as well as from purified proteins. The assay is based on the ability of TEV Protease to cleave a synthetic Fluorescein-based peptide substrate to release fluorescein which can be easily quantified using a fluorescence microplate reader at Ex/Em = 490/560 nm.
This assay kit is simple, rapid and can detect as low as 50 ng TEV Protease activity in samples.
TEV protease assay protocol summary:
- add samples and standards to wells
- add reaction mix
- analyze with microplate reader in kinetic mode for 15-30 min -
Notes
This product is manufactured by BioVision, an Abcam company and was previously called K842 TEV Protease Activity Assay Kit (Fluorometric). K842-100 is the same size as the 100 test size of ab211109.
TEV Protease (Tobacco Etch Virus protease, EC: 3.4.22.44) is a cysteine protease that recognizes the cleavage site of Glu-Xaa-Xaa-Y-Xaa-Gln-(Gly/Ser) and cleaves between Gln and Gly/Ser. The optimal sequence is Glu-Asn -Leu-Tyr-Phe-Gln-Ser/Glycine (ENLYFQS/G). TEV Protease has high specificity and great stability and is active over a wide range of temperatures (4-37°C) with an optimal activity at 34°C.
