<p>D-Melibiose monohydrate is a type of sugar that can be found in the extracellular space. It is also a component of fatty acids and has been shown to act as a growth factor for some cell types. D-Melibiose monohydrate has been characterized using tissue culture, growth factor profiles, and fluorescence detector. This sugar can be used as an alternative to trehalose in vitro assays, where it has been shown to have similar biological properties. D-Melibiose monohydrate may also be used for the manufacture of solid dispersions due to its solubility in organic solvents.</p>

<p>Zymosan is prepared from the cell walls of baker's yeast (Saccharomyces cerevisiae) and consists of polysaccharide chains of various molecular weights, containing approximately 73% polysaccharide, 15% protein, 7% lipid and other inorganic components. When injected into animals, it induces inflammation and has been used for many years in inflammation and immunology research. The conditions activated include components of the complement system, prostaglandins and leukotrienes, platelet aggregation factor, and lysosomal enzymes. Zymosan preparations are often insoluble but can be made soluble for separation on DE cellulose or Sepharose to produce more active fractions.</p>

<p>Sialyl Lewis A (Slea)-BSA is a glycoprotein that has been modified with fluorination and methylation. These modifications have been shown to enhance the binding of Sialyl Lewis A (Slea)-BSA to CD22, a cell-surface protein that is expressed on B cells. In addition, the modification of Slea-BSA with Click chemistry has been shown to increase its stability in plasma. This product may be custom synthesized to suit your needs.</p>

<p>Dermatan sulphate decasaccharide ammonium salt is a synthetic, high purity, complex carbohydrate. The CAS number for this product is 543-58-2. Dermatan sulfate decasaccharide ammonium salt is a complex carbohydrate that has been modified with a fluorine atom at the C1 position of the glucose monosaccharide and an acetyl group at the C4 position of the glucuronic acid monosaccharide. Click chemistry was used to introduce these modifications on the sugar molecule and it has been found to be stable in both acidic and alkaline conditions. This product can be customized for your specific needs, including fluorination, methylation, or glycosylation at any position.</p>

<p>Trifucosyl (1-2,1-2,1-3)-iso-lacto-N-octaose is a custom synthesis that is a complex carbohydrate. It is an oligosaccharide that contains three monosaccharides linked by alpha glycosidic bonds. This compound has been modified using methylation and glycosylation reactions. Trifucosyl (1-2,1-2,1-3)-iso-lacto-N-octaose has been fluorinated at the C6 position of the sugar ring to increase its solubility in water and enhance its stability in acid conditions. The product is a high purity synthetic compound.</p>

<p>Monofucosyl (1-3)-iso-lacto-N-octaose is an HMO oligosaccharide.</p>

<p>N-GlcNAc-Biotin is a biotin analog that is used for the detection of cancer. It is used as an outpatient diagnostic tool to detect chest deformity, asymmetry, and other signs of lung or breast cancer. N-GlcNAc-Biotin binds to the receptor for biotin, which is expressed on many cancers cells. The molecule then emits radiation at a specific wavelength that can be detected by a waveguide device. A recrystallized form of this compound was developed to enhance its sensitivity and specificity for diagnosis.END&gt;</p>

<p>Chitopentaose is a pentaacetyl derivative of the sugar chitohexaose. It is an oligosaccharide that has been shown to inhibit the activity of glycosidases and lectins, which may be due to its high affinity to these enzymes. Chitopentaose has also been found to bind to insulin receptors in the human tumor cell line A-20, leading to a reduction in tumor growth. The molecule also inhibits the transcriptional regulation of genes encoding for penicillin-binding protein, mouse tumor necrosis factor, and α1-acid glycoprotein.</p>

<p>Used to differentiate microorganisms based on their metabolic properties.</p>

<p>Man-8D1D2 N-glycan is a synthetic glycan that is used as a monosaccharide or polysaccharide. This product is produced through the modification of the natural Man-8D1D2 glycan by the addition of fluorine atoms and methyl groups to the sugar, making it a useful reagent for chemical synthesis. The purity of this product is high and its CAS number is 56612-59-6.</p>

<p>Agarose is a polysaccharide found in red algae, typically Gelidium and Gracilaria. It is a strictly alternating polysaccharide of α-1,3 linked D-galactose and β-1,4 linked L-3,6 anhydrogalactose with occasional sulfation at position 6 of the anhydrogalactose residue. Agaro-oligosaccharides result from cleavage at galactose residues and neoagaro-oligosaccharides from cleavage at 3,6-anhydro residues. Neoagarohexaose is reported to have potential for novel cosmeceuticals.</p>

<p>6-O-(2-Acetamido-2-deoxy-b-D-glucopyranosyl)-D-galactopyranose is a disaccharide that has been shown to have anti-inflammatory activities. It contains an acetamide group and a hydroxy group. The acetamide group is substituted by a hydroxy group, which may be responsible for its anti-inflammatory activity. 6-O-(2-Acetamido-2-deoxy-b-D-glucopyranosyl)-D-galactopyranose has also been shown to inhibit the production of proinflammatory cytokines such as tumor necrosis factor alpha (TNFα) and interleukin beta (ILβ).</p>
