The influence of monogalactosyldiacylglycerols from different marine macrophytes on immunogenicity and conformation of protein antigen of tubular immunostimulating complex

► Impact of MGDG on YOmpF conformation depends on lipid microviscosity. ► MGDG with medium fluidity moderately influenced tertiary structure of porin. ► Moderate conformational changes of porin provide maximal immunostimulating effect.
