Carboxymethyl cellulose
CAS:Carboxymethyl cellulose is used in food as a viscosity modifier, thickener, to stabilise emulsions and are found in gluten-free and reduced-fat products. It is also a constituent of toothpaste, laxatives, diet pills, water-based paints, detergents, textile sizing, and various paper products. In laundry detergents, it is used as a soil suspension polymer. It is also used in pharmaceuticals as a thickening agent and in the oil-drilling industry as a viscosity modifier and water-retaining agent.
Formula:C8H16O8Purity:Min. 95%Color and Shape:White PowderMolecular weight:240.21 g/molGum arabic
CAS:Gum arabic is an exudate gum picked from Acacia trees growing in tropical arid regions (typically Acacia senegal and Acacia laetia). The polysaccharide is branched with a main chain of (1-3) linked β-D-galactopyranosyl units with side chains of (1-3) β-D-galactopyranosyl units joined to it by (1-6) links. The side chains are 2-5 units in length. Both the main chain and the side chains have attached units of α-L-arabinofuranosyl, α-L-rhamnopyranosyl, β-D-glucuronopyranosyl and 4-O-methyl-β-D-glucuronopyranosyl units.Purity:Min. 95%Color and Shape:PowderGlucurono-xylomannan polysaccharide from Tremella fuciformis
CAS:The polysaccharide, known as glucuronoxylomannan - produced by fruit bodies and in pure culture conditions - has been shown to consist of a mannan backbone that is glycosylated with xylan and glucuronic acid chains in a regular repeating structure. Laboratory tests have associated a number of biological activities with Cryptococcus neoformans glucuronoxylomannan, including immunostimulatory, antidiabetic, anti-inflammatory, hypocholesterolemic, hepatoprotective, and antiallergic effects.

CAS:Viscoelastic polymer; excipient; food additiveDextran 70 - MW 64,000 to 76,000
CAS:Dextran is α-(1,6)-linked α-D-glucan with α-(1,3)-linked glucose branch points produced by fermentation of Leuconostoc mesenteroides via the action of the enzyme dextransucrase on sucrose. The main use for native dextran is as an extender in blood transfusions and products having a range of sharp cut-off molecular weights are produced commercially for this and other applications. A complex of Iiron with dextran, known as iron dextran, is used as a source of iron for baby piglets which are often anaemic at birth.Color and Shape:White Off-White PowderOctyl-agarose, contain 20% ethanol solution
CAS:Octyl-agarose is a type of agarose gel that has been modified to contain 20% ethanol solution. It is used in the purification of oligosaccharides and monosaccharides, as well as in the synthesis of complex carbohydrate. Octyl-agarose can be custom synthesized or modified with glycosylation, methylation, sugar, or carbohydrate modifications.Color and Shape:Slightly Turbid LiquidRhodamine B isothiocyanate-dextran - Average MW 10,000
Rhodamine dextran (RD) is widely used as both an anterograde and retrograde tracer in neurons and for numerous other applications. It is biologically rather inert having α-1,6-linked glucose residues resistant to cleavage by most endogenous cellular glycosidases. It has low immunogenicity and makes an ideal long-term tracer for live cells. RD also serves as a valuable marker for cell loading of macromolecules by micro-injection, vesicular fusion, and electroporation, as well as for the uptake and internal processing of exogenous materials by phagocytotic and endocytic pathways.Color and Shape:PowderCarboxymethyl-dextran sodium salt - Average MW 4,000
CAS:Sodium carboxymethyl dextran is a white, odourless and tasteless powder, which is freely soluble in water or electrolyte solutions. Applications that have been described for carboxymethyl dextran include carriers of paramagnetic contrast agents, preparation of conjugates of pharmacologically active compounds and carboxymethyl dextrans in biosensors. A number of other uses in cosmetics, agriculture, foods, paints and textiles have been the subject of patent applications.Color and Shape:PowderXylan - from corncob, MW 300-900
CAS:In their simplest forms, xylans are linear homopolymers of β-1,4-xylose residues. In nature they are partially substituted by acetyl, 4-O-methyl-D-glucuronosyl and α-1,3 L-arabinofuranosyl residues, forming complex heterogenous and polydispersed glycans. An example of this is in the L-arabino (methyl-D-glucurono) xylan from corn cob.Purity:Min. 95 Area-%Color and Shape:White Yellow PowderExopolysaccharide - from Bacillus polymixa
Bacterial exopolysaccharide from gram negative Bacillus polymixa

CAS:Laminaran is a polysaccharide that co-occurs with fucoidan and alginate in brown seaweeds such as Laminaria digitata, Laminaria cloustoni, Eisenia bicyclis and Thallus laminariae. It is a β-1,3-linked glucan which it is claimed stimulates the immune system in mammals and fish.

CAS:Isolichenan is a cold-water soluble (1,3)-(1,4)-α-D-glucan isolated from lichen Cetraria islandica to have MW of about 6-8 kDa. Lichens produce isolichenan-type polysaccharides with considerable variation in linkage ratios as well as MW, even within the same species. Occasionally these α-glucans can be branched at O2, O3 or O6. The immunomodulating activity of isolichenan was tested in in vitro phagocytosis and anti-complementary assays, and proved to be active in both cases.

CAS:The sugar component consists of alternating residues of β-(1,4) linked N-acetylglucosamine and N-acetylmuramic acid. A peptide chain of three to five amino acids is attached to the N-acetylmuramic acid. The peptide chain can be cross-linked to the peptide chain of another strand forming the 3D mesh-like layer.Color and Shape:PowderAmylopectin - from maize
CAS:Amylopectin is composed of between 2,000 to 200,000 glucose residues linked α (1→4) with α (1→6) branching. The molecule is highly branched, every 24 to 30 glucose units, resulting in a soluble molecule with many terminal residues. Starch is made of about 70% amylopectin by weight, though it varies depending on the source (higher in medium-grain rice to 100% in glutinous rice, waxy potato starch, waxy corn, and lower in long-grain rice, amylomaize, and russet potatoes).
Color and Shape:PowderWheat starch
CAS:Starch is an energy storing polysaccharide produced by higher plants and some algae. Pure starch is a white, tasteless and odorless powder that is insoluble in cold water or alcohol. It consists of two types of polysaccharide: the linear and helical amylose (α-1,4-linked glucose) and the branched amylopectin (α-1,4 and α-1,6-linked glucose). Depending on the plant, starch generally contains 20 to 25% amylose and 75 to 80% amylopectin by weight.Purity:Min. 95%Color and Shape:PowderGum karaya
CAS:Gum karaya is exuded from Sterculia urens, a bushy tree found in dry regions of North India. Due to its extensive swelling capacity in water it is used as a laxative and as a denture adhesive. The structure consists of D-galactose, D-glucuronic acid and L-rhamnose but the detailed molecular structure is still incompletely known.
Purity:Min. 95%Color and Shape:PowderDextran sulfate sodium - MW 5,000-8,000
CAS:Dextran sulphate is a dextran derivative whose ulcer (colitis) -causing properties were first reported in hamsters and extrapolated a few years later to mice and rats. The exact mechanisms through which dextran sulphate induces intestinal inflammation are unclear but may be the result of direct damage of the monolayer of epithelial cells in the colon, leading to the crossing of intestinal contents (for e.g. commensal bacteria and their products) into underlying tissue and therefore induction of inflammation. The dextran sulphate sodium induced ulceration model in laboratory animals has some advantages, when compared to other animal models of colitis, due to its simplicity and similarities to human inflammatory bowel disease.Formula:(C6H7Na3O14S3)nPurity:Min. 95%Color and Shape:Powder(Hydroxypropyl)methyl cellulose - USP39, Viscocity 3000-5600 cP
