Inhibition of CSFV binding to PK15 cells by recombinant expressed full-length or partial E2 proteins. For this purpose, the full-length E2 protein and domain B/C (E2_B/C) were used. The numbers within the names of the E2 constructs refer to the protein amounts (µg) per 24-well. The data represent the mean and standard deviation of three independent experiments. Values with different superscript letters, a–c, indicate a statistically significant difference (p < 0.05) from each other. The superscript letter “a” indicates the highest reduction of binding and “c” indicates unchanged binding to cells No significant differences exist between values containing the same letter.
