Preparing an Antigen-Adjuvant Emulsion to Induce Autoimmune Encephalomyelitis
Overview
This video demonstrates an efficient homogenization technique to generate an antigen-adjuvant emulsion to induce experimental autoimmune encephalomyelitis (EAE) in a murine model. The emulsion contains an autoantigen — myelin oligodendrocyte glycoprotein (MOG) — in the water phase, surrounded by a continuous oil phase comprising an inactivated pathogenic bacteria. The emulsion ensures a sustained release of antigens for a prolonged immune response.
Protocol
All procedures involving animal models have been reviewed by the local institutional animal care committee and the JoVE veterinary review board.
NOTE: A schematic flow of the method is described in Figure 1.
