GLYcoPROFILE technology was recently used in bacterial sialidases studies to screen a large range of inhibitors. Trough this method, polyvalent compounds based on the transition state sialyl cation 2-deoxy-2,3-didehydro-N-acetylneuraminic (DANA) have shown high affinity for sialidase from S.pneumoniae (NanA) from micromolar to picomolar range.
GLYcoPROFILE technology is an useful tool for characterisation of new ligands. A range of LEctPROFILE kits developed by GLYcoDiag are coming soon for your research needs (i.e. Sialylation (NeuAc, NeuGc, α2,3/α2,6), Galili, DC-SIGN & Langerin, …).
