Accounting for adjuvant-induced artifacts in the characterization of vaccine formulations by polyacrylamide gel electrophoresis

Several vaccine adjuvants comprise complex nano- or micro-particle formulations, such as oil-in-water emulsions. In order to characterize interactions and compatibility of oil-in-water emulsion adjuvants with protein antigens in vaccines, effective protein characterization methods that can accommodate potential interference from high concentrations of lipid-based particles are needed
