Investigation of Whole Cell Meningococcal Glycan Interactions Using High Throughput Glycobiology Techniques: Glycan Array and Surface Plasmon Resonance.

A growing body of evidence suggests that glycans are important for meningococcal host-pathogen interactions and virulence. The development of glycobiology techniques such as glycan array analysis and surface plasmon resonance (SPR) has increased awareness of the importance of glycans in biological processes and has increased the interest of their study. While these techniques are more routinely used with purified proteins, there is growing interest in their applicability to cell-based studies, to better emulate host-pathogen interactions in vivo. Here we describe the use of glycan array analysis and SPR for the investigation of glycan binding by Neisseria meningitidis cells. Used together, these methods can help identify and characterize N. meningitidis glycointeractions.
