Figure 5From: A reaction-diffusion model of the receptor-toxin-antibody interactionEffect of toxin diffusivity on antibody protection factor. Toxin diffusivity κ T = 10-2 (1), κ T = 5 · 10-3 (2), κ T = 10-3 (3), κ T = 10-4 (4). Horizontal line corresponds to value of ψsat given by Eq. (7) for curve 3.Back to article page
