Entry efficiency of pseudoviruses based on SARS-CoV-2 variants in HeLa cells expressing eACE2 or hACE2

(A) The work flow of pseudovirus infection assay of SARS-CoV-2 variants.

(B) The values show the variant change ratio in luciferase activity for each indicated mutated pseudovirus variant compared with WT D614G. Values over 100% indicate an increase, and those lower than 100% indicate a decrease. Results were calculated from two independent experiments performed in technical duplicates (n = 2) and represent mean ± SD.
