Representative immunohistochemical images of IgG+ immunoreactivity at the interface of microelectrodes sterilized by autoclave, dry heat or ethylene oxide gas at 2 weeks (A–C) and 16 weeks (D–F) post implantation. Quantification of IgG at 2 weeks (G) shows significantly higher accumulation of IgG was observed between 0–100μm for microelectrodes sterilized by autoclave compared to microelectrodes sterilized by dry heat or ethylene oxide gas. (H) No statistical difference was observed at 16 weeks post implantation regardless of initial endotoxin levels. Scale Bar = 100μm; * p<0.02
