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).

  • Removal of affinity purification tags such as maltose-binding protein (MBP) or poly-histidine from fusion proteins
  • Engineered to prevent autolysis and improve stability
  • Optimal activity and stability for up to 24 months
  • Active in a wide range of buffers; optimal activity between pH 6.0 and 9.0.
  • High substrate specificity with no non-specific proteolysis
  • TEV Protease contains a 7x His-Tag for easy removal from a reaction using NEBExpress® Ni Resin (NEB# S1428S), NEBExpress® Ni Spin Columns (NEB# S1427S/L), or NEBExpress® Ni-NTA Magnetic Beads (NEB# S1423S)

TEV Protease is a highly specific cysteine 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). It is often used for the removal of affinity purification tags such as maltose-binding protein (MBP) or poly-histidine from fusion proteins. TEV Protease has a 7xHis-tag for easy removal from a reaction using nickel affinity resins and has been engineered to improve thermal stability and decrease autolysis.

  • Engineered to improve thermal stability and decrease autolysis
  • High substrate specificity with no non-specific proteolysis 
 
An exception occurred during the operation, making the result invalid. Check InnerException for exception details.

Notes
  • The TEV Protease recognition sequence with the highest catalytic efficiency is ENLYFQ ▼S; however, the amino acid in the P1’ position (S in the recognition sequence) can also be G, A, M, C, or H (1).
  • 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.
  • TEV protease can be used at high concentrations without the occurrence of non-specific proteolysis.
  • Reactions may be scaled-up linearly to accommodate larger reaction volumes.

FAQs
Tech Tips
    • The optimal pH range is 6.0 – 8.0
    • Optimal activity achieved in ≤0.2M NaCl; however, the enzyme retains some activity in up to 2M NaCl
  • Cleavage at lower temperatures, such as 4ºC, requires overnight incubation

  • Inhibition occurs in the presence of ≥ 5 mM Zn2+, ≥ 1 mM Cu2+ and ≥ 10 mM Co2+

    • Compatible with 10mM MgSO4, MnCl2 and CaCl2 and up to 100mM EDTA
    • Compatible with the following protease inhibitors: aprotinin, benzamidine, leupeptin, pepstatin, PMSF
    • Can be used at high concentrations with no non-specific proteolysis occurring
    • Some substrates may require extended incubation (up to three days at either 4°C or 30°C)
    • If cleavage is not complete, add more TEV protease after 24 hours and continue incubation
