3C Protease Protein, HRV, Recombinant (His)
(Synonyms: rPSP, PSP, HRV 3C Protease) Copy Product InfoRecombinant PreScission Protease (rPSP) is a highly purified, restriction-grade 6×His-tagged protease derived from human rhinovirus 3C (HRV 3C). It specifically cleaves at the recognition sequence Leu-Glu-Val-Leu-Phe-Gln↓Gly-Pro (LEVLFQ↓GP), with the cleavage occurring between the Gln and Gly residues. This protease is commonly used to remove affinity tags from fusion proteins.
rPSP functions optimally at 30 °C, but retains activity at temperatures as low as 4 °C. Cleavage efficiency may vary with different fusion proteins, so optimization of enzyme amount, incubation time, and temperature is recommended. The His-tag allows easy removal of the protease after digestion using Ni²⁺ affinity chromatography.
The recombinant enzyme consists of 217 amino acids, has a molecular mass of approximately 24 kDa, and is produced through proprietary purification methods. It is fully biologically active.
