Table 1. Intracellular concentration of IA and release rates upon LPS activation.

	Conc [mM]	Release [fmol/cell/h]
RAW	8 [2]	2.34
BMDM	1.51	0.53

The concentration in RAW cells is derived from [2]. Release rates were determined based on medium concentration (Figure 1), viable cells and time after LPS activation.
