      Overview

      Description
      OverviewTag•off™ High Activity rEK is a highly purified preparation of the catalytic subunit of recombinant human enterokinase that recognizes the identical cleavage site as the native enzyme, AspAspAspAspLys↓ (Gasparian 2003). The Tag•off High Activity rEK substrate binding site (ArgArgArgLys) differs from the bovine enterokinase site (LysArgArgLys) by a single amino acid, which is believed to account for its higher substrate affinity and the resulting higher specific activity. The preparation has been functionally tested for activity with thioredoxin/human epidermal growth factor and thioredoxin/ human IL-13 fusion proteins (Gasparian). The Tag•off High Activity rEK as a highly purified (99% by Coomassie staining) enzyme solution and includes rEK 1X Dilution/Storage Buffer, 10X Cleavage Buffer, and a Cleavage Control Protein.
