A number of variables can be changed to optimize the cleavage of any specific protein. The amount of rTEV, the temperature of the incubation, and the time needed for cleavage may be examined. If the protein of interest is heat-labile, then 4oC incubations are recommended. Reactions at 4oC will require longer incubation times and/or more rTEV.
The rTEV contains 0.50 M Tris-HCl pH 8.0, 10mM DTT and 5 mM EDTA.
Sterile liquid formulation.
Greater than 90.0% as determined by:
(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE.
Store rTEV at -70oC for long term or at -20oC for< 6 months. Please prevent freeze-thaw cycles.
One unit of rTEV cleaves >85% of 3 ug control substrate in 1 h at 30oC.
