Remove fusion tags with restriction-grade site-specific proteases (e.g., Thrombin, Biotinylated Thrombin, Factor Xa, HRV 3C protease, Tag•off™ High Activity recombinant enterokinase [rEK], and rEK) and cleavage capture kits. EKapture™ and Xarrest™ agaroses are used for the removal of rEKs and Factor Xa, respectively, following cleavage of fusion proteins. Biotinylated thrombin is removed with streptavidin agarose and HRV 3C is removed with Ni-NTA agarose.
Features & Benefits
- Highly efficient, specific cleavage of fusion proteins
- Recombinant proteases (such as rEK) have higher activity than native protein
- Highly purified
- Functionally tested for activity, free of detectable contaminating proteases
- Supplied with cleavage control protein and buffers
- Capture kits also available
