TEV Protease Activity assay kit utilizes the ability of TEV Protease to cleave a synthetic Fluorescein-based peptide substrate to release fluorescein which can be easily quantified using a fluorometer or fluorescence microplate reader (Ex/Em = 490/560 nm). This assay kit is simple, rapid and can detect TEV Protease activity as low as 50 ng/well in viral lysates and purified protein samples.
TEV Protease (EC: 18.104.22.168, Tobacco Etch Virus protease) is a cysteine protease that recognizes the cleavage site of Glu-Xaa- Xaa-YXaa-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.
Detection of TEV Protease activity in viral lysates Determine activity of purified TEV Protease.
Store kit at -20°C, protected from light. Briefly centrifuge small vials at low speed prior to opening. Read entire protocol before performing the assay.TEV Protease Assay Buffer: Add 100 µl of 1 M DTT to the TEV Protease Assay Buffer. Mix well. Store at -20°C. Bring to room temperature before use.TEV Protease (Positive Control): Aliquot and store at -80°C. Avoid repeated freeze/thaw.
