  • Overview


    UniHRV 3C Protease is a recombinant form of the 3C protease derived from human rhinovirus 14 expressed in E. coli (specific activity 1800-2000 U/mg). This product is a highly purified recombinant 6XHis-fusion protein and requires neither metal nor cofactors for activity. UniHRV 3C Protease recognizes the cleavage site: Leu-Glu-Val-Leu-Phe-Gln↓Gly-Pro (LEVLFQ↓GP). UniHRV 3C Protease demonstrate excellent cleavage efficiency in a variety of fusion proteins.

    Product Note

    • Cleavage efficiency may differ based on structure and properties of each target protein, we recommend testing several enzyme-to-substrate ratios, temperatures and incubation times.
    • HRV 3C Protease reactions can be performed in a buffer which is optimal for the target protein. Reducing reagents (e.g., DTT) or salts (e.g., NaCl) can be added for cleavage efficiency evaluation.

    • Purity

      >98% as determined by SDS-PAGE analysis.

      Unit Definition

      One unit of HRV 3C Protease is defined as the amount of enzyme that will cleave >95% of 0.1 mg HRV 3C cleavage control protein in 150 mM NaCl, 50 mM Tris-HCl pH 7.5, at 4°C for 16 h.

    • Endotoxin level

      <1 EU per 1 μg of the protein by the LAL method.



  • Instruction
    • Reconstitution

      It is recommended to reconstitute the lyophilized protein in sterile H₂O and incubate the stock solution for at least 20 min to ensure sufficient re-dissolved.


      The product is shipped with polar packs. Upon receipt, store it immediately at -20°C or lower for long term storage.

    • Stability & Storage

      This product is stable after storage at:

      • -20°C for 12 months in lyophilized state from date of receipt.
      • -20°C or -80°C for 1 month under sterile conditions after reconstitution.

      Avoid repeated freeze/thaw cycles.
