chemical structureActive research projects in the group are focused on the challenging task of reproducibly creating nanomolar oligosaccharide based inhibitors for carbohydrate binding proteins, and the elucidation of the structural basis of unique molecular recognition of carbohydrate antigens by the immune system. Chemical synthesis and structural biology are central elements in nearly all projects.

To date successful outcomes have included a nanomolar inhibitor of the Shiga like toxin from E. coli O157:H7 (Nature, 403, 669-672, 2000) followed by a second generation approach that has resulted in a simplified molecule that can neutralize this toxin in-vivo (Proc. Natl. Acad. Sci (USA), 105, 16837-16842, 2008).

Research funding in the form of operating and equipment grants to support these general objectives is derived from several sources, Alberta Ingenuity and the Natural Science and Engineering Research Council (NSERC), Graduate students and postdoctoral fellows also hold competitive fellowships with some of these granting agencies.

Currently funded research projects include:

  • Multivalence assisted supramolecular assembly in biological sysytems
  • E. coli ┬áShiga-like toxins Stx-1 and Stx-2
    Glycoconjugate vaccines
    Candida albicans
    Brucella abortus, Brucella melitensis and Brucella suis

    Group facilities and special equipment

    tubesThe group is well equipped to carry out synthetic and biological aspects of research on complex carbohydrates. In addition to the standard items for performing organic chemistry, other equipment includes automated peptide synthesizer, preparative HPLC for organic and protein samples, titration microcalorimeter, UV and visible ELISA plate readers and washers, centrifuges, ultrafiltration devices and spectrophotometers. We maintain a dedicated tissue culture facility with the capability to grow mammalian cells in stationary flasks, roller bottles, shaker flasks and bioreactors. In addition to a full complement of PC to support routine work in the group, we utilizeDepartmental computer clusters and supercomputing facilities for molecular modeling.
