In cosmetics Global – Stand P105 – Paris 5-7 April 2022

Book in your calendar!!! GLYcoDiag will be present in the next In Cosmetics global 2022 in Paris porte de Versailles from Tuesday 5th to Thursday 7th April 2022 (Stand P105). GLYcoDiag will present the full services intended to microbiote studies and its technology platform GLYcoPROFILE®, intended to the research of new active products and the study of « glyco-actives » mechanisms relevant for cosmetic applications, which allow to reduce your time development and increase your innovation capability. Contact us to book a B2B meeting with us.

GLYcoPROFILE used in bacterial studies of Tropheryma whipplei infection

Divoly, A., Zarza, S. M., Landemarre, L., Roubinet, B., Decloquement, P., Raoult, D., Fournier, P.-E., Desnues, B. Human galectin-1 and galectin-3 promote Tropheryma Whipplei infection, Gut microbes, 2021, 13, e1884515 (DOI : 10.1080/19490976.2021.1884515).

 

GLYcoPROFILE was recently used for the characterization of Tropheryma whipplei, an actinobacterium which causes various infections in humans, including Whipple’s disease. Thus, the GLYcoPROFILE has enabled to characterize the glycan signature of T. Whipplei glycoproteins.

GLYcoPROFILE used to evaluate sialidases ligands efficiency

Polyvalent transition‐state analogues of sialyl substrates strongly inhibit bacterial sialidases.

Montembault, L. Fontaine, F. Daligault, J. Bouckaert, S. G. Gouin., A., Chem. Eur. J., 2020, (DOI : 10.1002/chem.202004672).

 

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, …).
