$395.00 – $795.00
Express 3CLpro with the T21I, C160F, A173V, V186A, and T304I mutations 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) T21I + C160F + A173V + V186A + T304I mutation Expression Kit
Tong et al. reported a 4.9-fold increase in IC50 for GC376 using a FRET-based endpoint assay with this mutation (Tong et al. 2023). Pfizer reported a 28.5-fold increase in EC50 to nirmatrelvir using a biochemical assay (Pfizer Laboratories 2022).
