HRV 3C Protease
Highly efficient fusion tag removal at low temperature
Recombinant type 14 3C protease from human rhinovirus (HRV 3C) is a recombinant restriction-grade protease. HRV 3C is a highly purified recombinant 6XHis-fusion protein, that recognizes the same cleavage site as the native enzyme: LeuGluValLeuPheGln↓GlyPro. The small, 22-kDa size of the protease, optimal activity at 4°C, high specificity, and His•Tag® fusion make HRV 3C protease an ideal choice for rapid removal of fusion tags. The pET expression vectors pET-47b(+) through pET-50b(+) incorporate the HRV 3C protease cleavage site in combinations with His•Tag, S•Tag™, thioredoxin (Trx•Tag™), glutathione-S-transferase (GST•Tag™), and NusA (Nus•Tag™) sequences. The combination of pET-47b(+) to pET-50b(+) vectors for expression, HRV 3C protease for fusion tag cleavage, and Ni-NTA His•Bind® metal affinity chromatography for protein purification as well as protease and fusion tag removal allows production of recombinant proteins free of vector-encoded sequences. Other expression vectors, including the pET-52b(+) vector, the InsectDirect™ pIEx™-9 vector, and the multisystem pTriEx™-6 vector, all incorporate the HRV 3C protease cleavage site in combination with the Strep•Tag® II and His•Tag sequences. Supplied as: 1.8-3.0 U/µl in 50 mM Tris-HCl (pH 8.0), 150 mM NaCl, 1 mM EDTA, 0.5 mM THP, and 50% glycerol.
