Rapid, reliable, and reproducible cell fusion assay to quantify SARS-Cov-2 spike interaction with hACE2

Fig 5

Correlation between the cell fusion and pseudotyping assays.

IC₅₀ values of the 17 serum samples to inhibit cell-cell fusion between TZMbl-Spike producer and HOS-3734 target cells are shown; note log scale of Y-axis (A). IC₅₀ values of the 17 serum samples to inhibit pseudotying virus entry are shown (B). Correlation between cell fusion and pseudotyping IC₅₀ values (C).
