The post-translational modification which is the most abundant in nature is the glycosylation of proteins. This modification affects deeply a protein: it can alter its function, stability, conformation and half-life in serum. The glycosylation of a protein is a complex process involving numerous enzymes: glycosidases and glycosyltransferases. As a result, glycoproteins can have very different patterns of glycosylation, even while using the same cell lines, according to the conditions used. For example, recombinant glycoproteins have gained an important share of the pharmaceutical industry output. The complexity of glycans, their physicochemical properties and involvement in major biological functions make glycomics the next challenge. Some applications: Recombinant therapeutic glycoproteins, glycosylated biomarkers, biofilms characterization, glycomimetic drug discovery, quality control.
GLYcoDiag expertise can help you decipher the glycoprofile of your samples molecules. By outsourcing this important analysis, you will speed up your projects and gain time and money.
Our specialised technology platform allows the identification and comparison of specific glycosylation profiles by monitoring the interactions of your molecules with a selected range of lectins.
Currently the methods used for glycan analysis require high level of expertise. Setting up a glycoanalysis platform involves large investments in equipment and experts. Our technology platform allows to draw a specific signature of the glycan pattern using lectins. Lectins are a family of carbohydrate-binding proteins that interact specifically with a wide range of sugars or glycan motifs We use a range of lectins to identify the main structures present at the surface of your protein. With this identification of specific "glyco-parameters", your protein glycoprofile can be also be part of a patent, giving added value to the characterisation of your protein.
Our technology has been developed by specialists in glycobiology in order to be user-friendly for non-specialists.
GLYcoDiag has developed strong links with Greenpharma S.A., a French company providing products and R&D contracts to pharmaceutical and cosmetic companies. Greenpharma exploits biodiversity ressourses within its innovative platform combining pharmacognosy with reverse pharmacognosy. Greenpharma in close partnership with GLYcoDiag will endeavour to discover and purify new plant lectins which are unique tools for glycoanalysis.
