EK-Away™ Resin is specifically designed for removal of EKMax™ or other enterokinase enzymes following cleavage of proteins containing the enterokinase cleavage site (Figure 1). The resin is conjugated with soybean trypsin inhibitor, which has a high affinity and binding capacity for enterokinase. The enzyme catalytic site binds this agarose-based resin for simple batch or column-bound removal of EKMax™ or other enterokinase preparations.
