<p>GT1c oligosaccharide (free acid) has a core tetrasaccharide structure (Galβ1,3GalNAcβ1,4Galβ1,4Glc) with three sialic acid residues (NeuAc) linked α2,8/α2,8/α2,3 to the inner galactose residue (Ledeen, 2009). A monoclonal antibody, established against the chick neural tube, was shown to recognize the trisialosyl residue, NeuAca2-8NeuAca2-8NeuAca2-3-R GT1c ganglioside in the cerebral cortex of fetal rats (Hirabayashi, 1989). This unusual multisialo ganglioside was recognised in chicken optic lobes and cerebrum, during embryonic development (Rosner, 1980) and in fish brains (Yu, 1980).</p>

<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>

Methylation of polysaccharides is the process of adding methyl groups to chemical compounds. This process can be achieved by using a variety of reagents. One type of reagent is a methyl donor, which is capable of transferring a methyl group to another molecule. The Methylation Kit contains various reagents that allow for the efficient and specific modification of polysaccharides, including carbohydrates, oligosaccharides, and saccharides. The kit includes two types of reagents: Methyl donors and Methyl acceptors. The kit also contains other additives such as solvents, buffers, and pH indicators.

Hyaluronic acid is a polysaccharide containing repeating disaccharide units of β-1,3-N-acetyl glucosamine and β-1, 4-glucuronic acid. A series of unsaturated oligosaccharides (oligouronic acids) are released from hyaluronic acid by the action of hyaluronidase on umbilical cord (Weissman, 1954). This hexasaccharide and other enzymatically produced polymer homologs have been of value in the study of hyaluronic acid metabolism in healthy and diseased tissues (Hascall, 2019).

The methylation of a glycosylation is an organic chemistry technique that can be used to modify the chemical structure of a carbohydrate. A glycosylation is the reaction between an alcohol and a sugar, which produces a glycoside. The addition of methyl groups at specific positions on the sugar molecule can lead to improved properties such as increased stability, increased solubility, or increased uptake by cells. This process has been shown to produce compounds with more desirable pharmacological properties than their parent compounds. Click chemistry is a versatile and powerful method for modifying carbohydrates. It involves the use of copper-catalyzed azide-alkyne cycloaddition reactions to form carbon-nitrogen bonds in place of conventional amide linkages in peptides and proteins. Carbohydrates are modified using this method by attaching small molecules such as fluorine atoms onto one or more carbons in the carbohydrate structure. This process can be used to create novel sugars with improved properties including high purity, high stability
