Carbohydrates and glycoconjugates

<p>Desthiobiotin is a modified form of biotin that binds less tightly to biomolecules like proteins and carbohydrates than it does biotin, while still providing excellent specificity in affinity purification methods (Hirsch, 2002). The structure of GD2-oligosaccharide-desthiobiotin (sodium salt) comprises (GalNAcβ1,4Galβ1,4Glc) of its two sialic acids linked α2,3/α2,8 to the central galactose residue (Ledeen, 2009). The desthiobiotin is attached β to position 1 of the reducing glucose moiety. GD2 ganglioside is expressed at a low concentration in the central nervous system, nerves, skin melanocytes and stem cells in healthy adults. On the other hand, GD2 ganglioside is overexpressed in a number of tumors including: neuroblastoma, melanoma, small cell lung carcinoma and brain tumors. Recently, GD2 ganglioside has been found in low concentration on breast cancer stem cells (CSC) that possess: self-renewal properties (division without disrupting the undifferentiated state) and tumor-initiating capabilities. It has been suggested that GD2 ganglioside may be developed as an effective target antigen for CSC immunotherapy (Fleurence, 2017).</p>
