Fig 1. Antimicrobial activity of FLG2 C-terminal fragments tested against various bacteria in the radial diffusion assay.

The corresponding amino acids of the full length protein are indicated below each fragment. The MEC is defined as the “minimal effective concentration” by the x-axis intersect in graphical analyses of clearing zones. The MECs stated represent the x-axis intersect of a regression calculated over all measured clearing zone units, the 95% confidence interval is indicated in parentheses; n = 3–12. Shaded gray: turbid clearing zones.
