Bar Plot from Scientific Research

The evaluation of 20 candidates. The MFI of FITC in the VOCs (Alpha, Beta, Gamma, and Delta) was shown in red column and that in the furin-S was shown in green column. Y453F, Q498H, and N501Y mutants were set as positive control (PC, blue column) while G502D mutant was set as negative control (NC, gray column). One site with no significance (n.s.) was shown in black column. Eleven tighter sites were shown in pale brown column and the eight tightest sites were shown in orange column. The t -test analysis was indicated as: n.s., P > 0.05, * P < 0.05, ** P < 0.01, *** P < 0.001.
