<p>Pentagalacturonic acid (α-1,4 galacturonopentaose) is derived from pectin or pectic acid, by enzymatic or partial acid hydrolysis (Combo, 2012). It is used in galacturonic acid metabolism research as a substrate to identify, differentiate and characterize endo- and exopolygalacturonase(s) and gluconase(s) (Jayani, 2005). The addition of very short fragments of homogalacturonan, tri-galacturonate, tetra-galacturonate, and penta-galacturonate oligosaccharides, restores development in dark-grown, de-etiolated seedling mutants, suggesting that they are unable to generate de-methylesterified pectin fragments. A model of spatiotemporally separated photoreceptive and signal-responsive cell types has been proposed that contains overlapping subsets of the regulatory network of light-dependent seedling development (Sinclair, 2017).</p>

It can be modified with fluorination or other modifications to meet your needs.</p>

<p>2-O-(2-O-(a-D-Mannopyranosyl)-a-D-mannopyranosyl)-a-D-mannopyranose is an oligosaccharide that is synthesized by the glycosylation of a D-mannose with 2,3,4,6-tetra‑O‑benzoyl‑beta‑D‑glucuronic acid. This product is available in custom synthesis and can be modified to order. It has been shown to be highly pure and can be used for a variety of applications including glycosylation reactions, methylations, fluorinations, click modifications, and complex carbohydrate studies.</p>

<p>GA1-ganglioside is also known as asialo-GM1 ganglioside. Autoimmune responses to GA1 ganglioside and high titers of anti-GA1 antibodies have been associated with neuromotor disorders, such as, motor neuron disease, multifocal motor neuropathy, and Guillain-Barré syndrome (Kolter, 2006). Anti-GA1 antibodies are also associated with Borrelia burgdorferi infection and Lyme disease (Djellaoui, 2016).</p>

Monofucosyl (1-3)-iso-lacto-N-octaose is an HMO oligosaccharide.

<p>D-Maltose monohydrate is a glycosylation product of maltose. It is a complex carbohydrate that has been methylated, fluorinated, and modified with Click chemistry. D-Maltose monohydrate has the CAS number of 3647-20-3 and can be custom synthesized to meet your specifications. This product is free from endotoxins and can be made in high purity.</p>

<p>The structure of GD2-oligosaccharide-sp-biotin (sodium salt) comprises (GalNAcβ1,4Galβ1,4Glc) with two sialic acids linked (β-2,3/β-2,8) to the central galactose residue and biotin attached 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, it has been found in low concentrations 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.</p>

<p>Lewis Y-O-(CH2)8-biotin is a carbohydrate with the chemical formula (CHO)(CO)3OH. It is a methylated and glycosylated oligosaccharide that has been custom synthesized for use in biotechnology applications. Lewis Y-O-(CH2)8-biotin has been fluorinated at the C5 position to improve its stability and prevent hydrolysis, which may be due to its high purity. This carbohydrate is not commercially available and must be custom synthesized.</p>

<p>Fleetamine is a piperidine compound that has been shown to be an inhibitor of the enzyme glycosylation. Inhibitors of glycosylation are useful for treating diseases such as diabetes and Alzheimer's disease. It is thought that Fleetamine may inhibit human glycosylating enzymes, such as glucosyl transferase, which catalyzes the addition of a glucose molecule to a protein. This inhibition prevents the formation of oligosaccharides and glycoconjugates, which are necessary for proper functioning of cells.</p>

Heparin is a complex carbohydrate that has been modified by the addition of a sugar and a sulfate group. It is used in the treatment of thrombosis, deep vein thrombosis, pulmonary embolism, and other blood clots. Heparin disaccharide IV-S disodium salt (HDS) is an intravenous form of heparin that consists of sodium salts of two saccharides: heparin disaccharide and sodium disulfate. HDS has been shown to be more potent than unfractionated heparin in animal models, as well as being more effective in preventing clot formation in humans. This drug also exhibits less frequent side effects such as skin rash, itching, or hives.
