#C1202N 3CLPro E166V Expression Kit

$395.00$795.00

Express 3CLpro with the E166V mutation in mammalian cells including HEK293, A549, and many more. Use alongside other 3CLpro mutant proteases and our 3CLglow biosensor assays to test 3CLpro inhibitor efficacy against a panel of mutations in the protease.


 

 

3CLpro (Mpro) E166V mutation Expression Kit

In a recombinant SARS COV-2 assay conducted in huh7-ACE2 cells, the E166V mutation demonstrates a 100-fold IC50 resistance to nirmatrelvir, albeit with a reduction in fitness (Iketani et al. 2023). This mutation has been detected in patients and reported to the GISAID database (Shu and McCauley 2017; Iketani et al. 2023). Interestingly, the prevalence of E166V is higher in subjects treated with nirmatrelvir compared to those in the control group (0.8% versus less than 0.2%, respectively) (Pfizer Laboratories 2022).

  • Identify protease inhibitors that maintain efficacy against the E166V mutation
  • Easy co-expression with our 3CLglow and 3CLglowUp sensors
  • Cost effective screening with minimal safety requirements (BSL-1)

Materials in the Kit:

• 3CLpro E166V in BacMam
• Sodium Butyrate, 500 mM in H2O
