Calcium buffer parameters and values.

Buffer^a		Values^b [31]
	[M	M^−1s^−1	m^2s^−1)	M
Endogenous	50		15	0.5
EGTA	0.18		220	2
BAPTA	0.22		220	2
ATP	2300		220	2

The buffered ion species is Ca²⁺ which is assumed to have a diffusion coefficient of 220 m²s⁻¹ and an external concentration of 1.3 mM [55].
= dissociation constant, = forward reaction rate, = diffusion coefficient, and . = total buffer concentration (bound and unbound).
