BackgroundRecombinant human rhinovirus(HRV)3C protease is widely used in the purification and productions of proteins due to its good stability，high specificity，and enzymatic activity．3C protease is one of the non—structural proteins of HRV，and plays important roles in the life cycle of HRV．This protease specifically recognizes the sequence Leu-Glu-Val-Leu-Phe-Gln-Gly-Pro, and cleaves the peptide bond between Gln and Gly. ComponentsStorage Solution: 1U/μl 3C Protease50mM Tris-HCl，150mM NaCl，10mM EDTA，1mM DTT，50%(v/v) glycerol（pH 8.0 @ 25℃）
10*Reaction Buffer: 500mM Tris-HCl，1.5M NaCl，10mM EDTA，10mM DTT，（pH 7.5@ 25℃） Protocol1. Combine 100 μg of fusion protein, 10 μl of 10*Reaction Bufferr and H20 (if necessary) to make a 100 μl total reaction volume.
2. Add 1 µl HRV 3C Protease
3. Incubate reaction at 5°C for 16 hour. GuidelinesPlease avoid repeated freeze-thaw cycles. Unit DefinitionOne unit is defined as the amount of enzyme required to remove > 90% of the GST label from 100 µg of fusion protein at 5°C for16 hour. bio-equip.cn AntBio is a biotechnology group company dedicated to serving life sciences, aiming to help scientists accelerate research and improve work efficiency.
