Interaction between DMBT1 and galectin 3 is modulated by the structure of the oligosaccharides carried by DMBT1

► DMBT1 was purified from intestinal tissue (proximal and distal) of healthy individuals. ► Glycosylation patterns of DMBT1 were identified by nano-ESI-Q-TOF. ► Determination of the kinetic parameters of DMBT1 to galectin 3, by SPR. ► Identification of the structural domains of galectin 3 that could interact with DMBT1.
