Figure 4From: A reaction-diffusion model of the receptor-toxin-antibody interactionEffect of the antibody diffusivity on the antibody protection factor. Antibody diffusivity κ A = 10-1 (1), κ A = 10-2 (2), κ A = 10-3 (3). Horizontal lines correspond to values of ψsat given by Eq. (7) for curves 1 and 2.Back to article page
