Because the candidate fraction identified in SDS-PAGE (Figure 5A) could be degradation products, we did not take the molecular weight into account. Purity by SDS-PAGE: 95%: Biological Activity: . Store 10X TEV Buffer at -20C. Further information regarding NEB product quality can be found, The Certificate of Analysis (COA) is a signed document that includes the storage temperature, expiration date and quality controls for an individual lot. [6] The substrate is held as a -sheet, forming an antiparallel interaction with the cleft between the barrels and a parallel interaction with the C-terminal tail. The P1 residue (Gln, red) of the substrate peptide (pink) interacts with the TEV protease S1 pocket residues (emphasized in rectangular boxes) through the hydrogen bonds (blue dotted . 0.5 mM EDTA *Excl. TEV protease leads to the cleavage of the TEV protease recognition site placed between the blocker moiety and the N-degron, resulting in the exposure of the destabilizing residue (Phe or Asp) located at the N-terminus. 250 mM NaCl If the fusion protein sample contains > 2 M urea, > 0.5 M Guanidine hydrochloride, > 50 mM imidazole, pH values below 6 or above 9, or cysteine protease inhibitors then it will be necessary to dialyze the fusion protein before TEV Protease cleavage. [10][12], Specificity is endowed by the large contact area between enzyme and substrate. three hours of cleavage reaction are mostly sufficient as prolonged incubation times do not lead to proportional increases of cleavage. BP TM TEV Protease has a specific activity of at least 10,000 units/mg, using the conventionally defined activity unit (One unit cleaves >85% of 3 g control substrate in 1 h at 30 o C). We use cookies to ensure that we give you the best experience on our website. TEV recognizes the amino acid sequence of the general form E-X-X-Y-X-Q (or S)/X', and cleaves between Q (or S)/X'.

Protean TEV Protease His6 is genetically modified 28 kDa recombinant protein. PPAR LBD was incubated with 6xHis-tagged TEV overnight and passed through Histrap FF columns again to remove the 6xHis tag and TEV protease. The TEV protease recognition sequence with the highest catalytic efficiency is ENLYFQ S; however, the amino acid in the P1 position can also be G, A, M, C, or H (1). Amino acids. The reason for the use of TEV protease as a biochemical tool is its high sequence specificity. Recombinant TEV Protease is a site-specific protease purified from E. coli by the affinity tag, GST tag. It is recommended that the cleavage for each fusion protein be optimized by varying the amount of Recombinant PreScission Protease, reaction time, or incubation temperature. The MBP-TEVP-rsTEV-EGFP-His 6 fusion protein not only was well induced but also correctly processed to yield MBP-TEVP-rsTEV and EGFP-His 6, respectively (Fig. One Unit of Numacut TEV protease cleaves 80% of 3 g control substrate in 1 hour at 30C and pH 8.0. Because of this new recognition site, your target is fused C-terminal to ENLYFQ and is cleaved-off by Numacut TEV protease independently of the N-terminal amino acid. The following is a list of Safety Data Sheet (SDS) that apply to this product to help you use it safely. PreScission Protease is a fusion protein of human rhinovirus (HRV) 3C protease and GST. BioVision's EZCut TEV Protease is an improved version of TEV protease that is highly site-specific, highly active, and significantly more stable than native TEV protease, resulting in enhanced long-term activity. [18] TEV protease shows loss of activity at temperatures above 34 C.[19]. The TEV Protease recognition sequence with the highest catalytic efficiency is ENLYFQ S; however, the amino acid in the P1 position can also be G, A, M, C, or H (1). Associated products.

Tobacco Etch Virus (TEV) protease is a cysteine protease enzyme with a molecular weight of 27 kDa. 50 mM Tris-HCl 250 mM NaCl 1 mM TCEP 1 mM EDTA 50% Glycerol pH 7.5 @ 25C Heat Inactivation 65C for 10 minutes Molecular Weight Apparent: 28 kDa Unit Assay Conditions Two fold dilutions of TEV Protease are incubated with 2 g MBP5-TEV-paramyosin Sal and 1X TEV Protease Reaction Buffer in a 10 l reaction. Increase the reaction time ( 24h) to improve the cleavage efficiency. The TEV protease optimum temperature is 30C, although it is active in relatively wide temperature range of 4-34C. Can TEV Protease be used at lower temperatures? Afterward, TEV protease was added to the protein sample at the ratio of 10:1 (w/w), incubated for 16 h on the shaker at 4 C to remove the GFP-His8-tag. 250 mM NaCl Peptides and proteins are guaranteed for 3 months from date of receipt. The following file naming structure is used to name these document files: [Product Number]_[Size]_[Version]_[Lot Number]. formation of soluble, high molecular weight aggregates of human papilloma virus E6 fused to MBP [7].
