Figure 5: Repeated free PEG injection does not cause runaway APA production in sensitized mice.

Figure 5:

Mice were first sensitized against PEG on Day 0 by the i.v. administration of empty PEGylated liposomes (0.1 μmole lipid / kg weight) and then given injections of PBS or free PEG 40 kDa (550 mg/kg, i.v.) on days 14, 21, 28, and 35. Serum was collected before each weekly infusion for APA measurements.
