Diffusion constants for diffusible molecules in the model.

<p>Molecules not listed do not diffuse; thus, their diffusion constants are zero. To calculate diffusion coefficients as in <a href="http://www.ploscompbiol.org/article/info:doi/10.1371/journal.pcbi.1002383#pcbi.1002383-Oliveira1" target="_blank">[57]</a> we used a cytosolic viscosity of 4.1 for small molecules and a cytosolic viscosity of ∼8.7 for proteins . These values yielded calcium gradients similar to those measured experimentally <a href="http://www.ploscompbiol.org/article/info:doi/10.1371/journal.pcbi.1002383#pcbi.1002383-Scheuss1" target="_blank">[59]</a>, and diffusion constants similar to those measured experimentally <a href="http://www.ploscompbiol.org/article/info:doi/10.1371/journal.pcbi.1002383#pcbi.1002383-Schmidt1" target="_blank">[50]</a>.
