SARS-CoV-2 3CLpro/3C-like protease Protein (N-His)
Based on 1 Customer Validation
SARS-CoV-2 3C-like Proteinase (His), His, expressed in E.coli, mediates viral polyprotein maturation and multiple cleavages of host proteins to modulate viral translation and transcription with a His tag at the N-terminus.
- Species: Virus
- Source: E. coli
-
Storage:Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Description
SARS-CoV-2 3C-like Proteinase (His), His, expressed in E.coli, mediates viral polyprotein maturation and multiple cleavages of host proteins to modulate viral translation and transcription with a His tag at the N-terminus[1].
Background
The 3C protease has been regarded as a valid target due to its structural similarity among different picornaviruses and minimal sequence similarity with host proteins; therefore, the development of potent inhibitors against the 3C protease as an antiviral drug is ongoing. Duck hepatitis A virus (DHAV) belongs to the Picornavidea family and is a major threat to the poultry industry[1].
Verified Bioactivity
Measured by its ability to cleave a fluorogenic peptide substrate, Dabcyl- KTSAVLQSGFRKME-Edans (Ssynthetic). The specific activity is >13000 pmol/min/mg.
