Product Information

Description

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.

Product Notes

  1. 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).
  2. 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.
  3. TEV protease can be used at high concentrations without the occurrence of non-specific proteolysis.
  4. Reactions may be scaled-up linearly to accommodate larger reaction volumes.

FAQs & Troubleshooting

FAQs

  1. Can TEV Protease recognize and cleave a sequence other than Glu-Asn-Leu-Tyr-Phe-Gln-(Gly/Ser)?
  2. Is it necessary to dialyze the sample prior to cleavage with TEV Protease?
  3. Can TEV Protease be used at lower temperatures?
  4. Is TEV Protease compatible with protease inhibitors?
  5. Is TEV Protease compatible with different reaction buffers?
  6. Can TEV Protease be removed from the reaction after cleavage?

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
