    • Properties & Usage

      Unit Definition

      1 unit is defined as the amount of enzyme required to cleave 25 µg of a MBP-EK-paramyosin-ΔSal substrate to 95% completion in 16 hours at 25°C in a total reaction volume of 25 µl.

      Removal

      Enterokinase will bind specifically to trypsin inhibitor agarose (e.g., Sigma T-0637).

      Storage Buffer

      20 mM Tris-HCl
      200 mM NaCl
      2 mM CaCl2
      50% Glycerol
      pH 7.2 @ 4°C

      Molecular Weights

      Apparent: 31 kDa
      Theoretical: 26.3 kDa

      Unit Assay Conditions

      Two fold dilutions of Enterokinase, light chain are incubated with 25 µg MBP-EK-paramyosin-ΔSal substrate in 20 mM Tris-HCl, 50 mM NaCl, 2 mM CaCl2 (pH 8.0 @ 25°C) in a 25 µl reaction. The reaction mix is incubated at 25°C for 16 hours. Separation of reaction products are visualized by SDS-PAGE.

    • Product Notes

      1. NaCl concentration above 250 mM will significantly inhibit enzyme activity.
      2. Removal: Enterokinase will bind specifically to trypsin inhibitor agarose (e.g., Sigma T-0637).
      3. Enterokinase is a glycosylated protein.
