Oligossacarídeos

GM3-ganglioside NBD (ammonium salt) has a core disaccharide structure (Galβ1,4Glc) with sialic acid linked α2,3 to the galactose residue with nitrobenzoxadiazole (NBD) linked β to position 1 on the reducing terminal glucose residue, in place of the ceramide fatty acid (Ledeen, 2009). Ganglioside GM3 is strongly associated with human tumors, such as, lung, brain, and melanomas, where it is frequently found to be overexpressed. GM3 ganglioside is seen as a possible tumor-associated carbohydrate antigen for cancer immunotherapy (Changping, 2019). GM3 ganglioside is implicated in various other diseases involving chronic inflammation, such as: insulin resistance, leptin resistance, T-cell function, and immune disorders (e.g. allergic asthma). It has also been shown to play an essential role in murine and human auditory systems, and is a common pathological feature of GM3S deficiency is deafness (Inokuchi, 2018).

3'-Sulfated Lewis X methyl glycoside is a synthetic, fluorinated oligosaccharide that can be used as a sugar or as an intermediate in the synthesis of complex carbohydrates. It is available for custom synthesis and modification to meet your specific needs. 3'-Sulfated Lewis X methyl glycoside is a monosaccharide that has been modified with a click reaction to attach sulfate groups. This modification allows for easier saccharide recognition and binding in the body. The CAS number for 3'-sulfated Lewis X methyl glycoside is 386264-50-2.

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).

1',6,6'-Trichloro sucrose is a complex carbohydrate that is synthesized from sucrose by the methylation of the hydroxyl groups followed by 1,6-dichlorination. This product has been shown to have a high degree of purity and can be used in a number of applications, including as a sugar substitute.
