Polysaccharides
Les polysaccharides sont des composés organiques formés par l'union de plusieurs monomères, liés entre eux par des liaisons glycosidiques pour créer de grandes molécules souvent ramifiées. Ces glucides complexes jouent des rôles cruciaux dans diverses fonctions biologiques, y compris le stockage d'énergie, le soutien structurel et la communication cellulaire. Dans cette section, vous trouverez une gamme variée de polysaccharides essentiels pour la recherche en biochimie, biologie moléculaire et glycosciences. Ces composés sont vitaux pour l'étude des voies métaboliques, des structures de la paroi cellulaire et du potentiel thérapeutique des glucides. Chez CymitQuimica, nous proposons des polysaccharides de haute qualité pour soutenir vos recherches scientifiques, garantissant précision et fiabilité dans vos résultats expérimentaux.

Diethylaminoethyl-dextran HCl
CAS :DEAE-Dextran hydrochloride (DEAE-D) is a positively-charged dextran derivative that can be used for vaccine production, gene therapy, protein stabilisation, dyslipidemia prevention, as flocculating agent, and many other applications. DEAE-D is also used for transfecting animal cells with foreign DNA. DEAE-Sepharose, DEAE-650 and DEAE-Sephadex are commonly used in chromatography for the separation of biological molecules such as proteins and carbohydrates.Degré de pureté :Min. 95%Couleur et forme :White Off-White PowderCarboxymethyl-dextran sodium salt - Average MW 70,000
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.Couleur et forme :PowderCellulose acetate - MW 30,000
CAS :Cellulose acetate fiber is one of the earliest synthetic fibers and is based on cotton or tree pulp cellulose. Cellulose acetate is used as a film base in photography, as a component in some coatings, and as a frame material for eyeglasses. It is also used as a synthetic fiber in the manufacture of cigarette filters and playing cards. In photographic film, cellulose acetate replaced nitrate film in the 1950s, being far less flammable and cheaper to produce but in recent years has been rendered obsolete by the advent of digital cameras.Couleur et forme :PowderSephadex G50
CAS :Sephadex G-50 is a highly purified, high molecular weight, cellulose-based polymer that is used as a solid support in chromatography. The size of the gel particles can be varied by changing the concentration of the gel solution. It has a number of different uses, such as purification of proteins and other macromolecules, separation of DNA fragments, and the enzymatic synthesis of oligosaccharides. Sephadex G-50 is a synthetic material that is modified with organic or inorganic compounds to increase its chemical reactivity. This product can also be used for glycosylation and methylation reactions.Couleur et forme :PowderHydroxyethyl Cellulose (200-300mPa·s, 2% in Water at 20°C)
CAS :Couleur et forme :White to Light red to Green powder to crystal(2R,3R,4R,5R)-2-amino-4-[(2R,3R,4R,5S,6R)-3-amino-5-[(2S,3R,4R,5S,6R)-3-amino-4,5-dihydroxy-6-(hydroxymethyl)oxan-2-yl]oxy-4-hydroxy-6-(hydroxymethyl)oxan-2-yl]oxy-3,5,6-trihydroxy-hexanal

CAS :Ulvans are structural polysaccharides present in the cell walls of green algae such as Ulva armoricana, Ulva rotondata, Ulva rigida, Ulva lacterca and Ulva pertusa. They are highly sulphated and contain rhamnose 3-sulphate, xylose, xylose 2-sulphate, glucuronic acid and iduronic acid residues. Ulvan has several potentially valuable functionalities such as gel formation for agricultural and food applications. It has also an anticoagulant, antioxidant, antihyperlipidemic and antitumor activities that are attractive for pharmaceutical applications. The image was kindly provided by Prof Mike Guiry from Cork who runs ‘The Seaweed Site’.Degré de pureté :Min. 95%Couleur et forme :Powder(Hydroxypropyl)methyl cellulose, viscosity 5 cP 80%-120%, 2% aqueous solution
CAS :Please enquire for more information about (Hydroxypropyl)methyl cellulose, viscosity 5 cP 80%-120%, 2% aqueous solution including the price, delivery time and more detailed product information at the technical inquiry form on this pageDegré de pureté :Min. 95%Gum 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.Degré de pureté :Min. 95%Couleur et forme :PowderPropylene glycol alginate
CAS :Propylene glycol alginate is a reaction product of propylene oxide and alginic acid. At the 49th JECFA meeting (1997) it was resolved that the total dietary propylene glycol intake from all sources should be allocated an ADI of 0-25 mg/kg. Applications include as a stabiliser in beer foam due to electrostatic interaction between carboxyl groups on the glycol alginate molecules and amino groups on the peptides in the bubble wall and in ice cream by emulsifying the fat.Esterification is greater then 80%Viscosity (1% aq solution): 200-300 mpa.sDegré de pureté :Min. 95%Couleur et forme :PowderD-(+)-Cellopentaose

CAS :N-Acetyl-de-O-sulphated heparin is a glycosaminoglycan, which occurs in many mammalian tissues and has important anticoagulant and thrombolytic properties. The chemical structure is composed mainly of two disaccharide repeating units A and B. A is L-iduronic acid 2-suplhate linked α-(1,4) to 2-deoxy-2-sulfamido-D-galactose 6-sulphate, while B is D-glucuronic acid β-(1,4) linked to 2-deoxy-2-sulfamido-D-glucose 6-sulphate.Degré de pureté :Min. 95%Couleur et forme :Powder
