Protocol for TEV cleavage
written by NZ
cleaves proteins at specific sequence E-X-X-Y-X-Q-G/S between Q and G/S, with best sequence ENLYFQG
buffer
- 50 mM Tris-HCl pH 8.0
- 0.5 mM EDTA
- 1 mM DTT
- can tolerate up to 100 mM NaCl
cleavage conditions
- optimize according to sample, but here are starting conditions that have worked
- dialyze/resuspend/elute protein sample from 1L culture in 10-25ml TEV buffer
- add 0.5-1 mg TEV
- incubate for 1-3 hr at RT or 3 hr – overnight at 4C
