Starch from potato
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.Color and Shape:White PowderEthyl cellulose
CAS:Ethyl cellulose is similar in structure to methyl cellulose with ethyl replacing the methyl groups. It is approved for use in regulated markets such as food and pharmaceuticals. In pharmaceuticals it can mask the taste of bitter actives, enhance the strength and appearance of tablets and capsules, and enable controlled release formulations. In food products it functions as a binder, film former and flavour fixative.Purity:Min. 95%Color and Shape:White Yellow PowderChitosan - Molecular weight 50,000-190,000
CAS:Chitosan is the deacetylated form of chitin. The polysaccharide is deacetylated in order to render it soluble, which is then possible at pH values of less than 7 (normally in dilute acid). This then allows the material to be used in a number of industrial applications as a binder and film former.Color and Shape:PowderTara gum
CAS:Tara gum is a galactomannan that is obtained from the seeds of the tara shrub Caesalpinia spinosa which is a native of the northern regions of Africa and South America. The gum is described as having a backbone of (1,4)-linked β-D-mannopyranosyl units one third of which possess a single unit side chain of (1,6)-linked α-D-galactopyranose. The gum forms gels with carrageenan and xanthan in a similar manner to guar and locust bean gum. Currently, only small quantities of tara gum are sold for use as food thickeners and stabilisers.Purity:Min. 95%Color and Shape:PowderBacterial alginate - from fermentation of Azotobacter vinelandii or Pseudomonas mendocina
An alginate-like polysaccharide produced by the fermentation of Azotobacter vinelandii or Pseudomonas mendocina. The chemical structure consists of blocks of (1,4) linked-β-D-polymannuronic acid (poly M), (1,4) linked-α-L-polyguluronic acid (poly G) and alternating blocks of the two uronic acids (poly MG). Unlike the alginate from seaweed, this polysaccharide is partially acetylated.Color and Shape:PowderMolecular weight:~100KDaDextran 5 - MW 4,000 to 6,000
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 iron with dextran, known as iron dextran, is used as a source of iron for baby piglets which are often anaemic at birth.

CAS:In water, hydroxypropyl cellulose forms liquid crystals with many mesophases depending on concentration. These mesophases include isotropic, anisotropic, nematic and cholesteric, the latter resulting in many colors such as violet, green and red. Pharmaceutical applications include treatments for medical conditions such as dry eye syndrome (keratoconjunctivitis sicca), recurrent corneal erosions, decreased corneal sensitivity, exposure and neuroparalytic keratitis. It is also used as a binder in tablets. Hydroxypropylcellulose is also used as a thickener, a binder and emulsion stabiliser in foods with E number E463. HPC is used as a support matrix for DNA separations by capillary and microchip electrophoresis.Purity:Min. 95%Fluorescein isothiocyanate-dextran - Average MW 70,000
CAS:Anterograde and retrograde tracer in neurons; biologically inertPurity:Min. 95%Glycogen - from oyster for molecular biology
CAS:Glycogen is a highly branched polysaccharide of glucose that serves as a form of energy storage in animals and fungi. It is the main storage form of glucose in the body. In humans, glycogen is made and stored primarily in liver and muscle cells and functions as the second most important energy storage molecule to fat which is held in adipose tissue. Glycogen is analogous to starch and has a structure similar to amylopectin, but is more extensively branched and compact than starch. It occurs as granules in the cytosol/cytoplasm in many cell types, and plays an important role in the glucose cycle.
Purity:Min. 95%Cellulose acetate hydrogen phthalate
CAS:Cellulose acetate phthalate (CAP) finds use in the formulation of pharmaceuticals, such as the enteric coating of tablets or capsules and for controlled release formulations, where it is often used with other coating agents such as ethyl cellulose. It contains about 50% acetate and 25% as the phthalate ester with the rest as free hydroxyl groups. Enteric coatings based on CAP are resistant to acidic gastric fluids, but easily soluble in mildly basic medium of the intestine. The pH-sensitive solubility of CAP is mainly determined (as are other properties of this mixed ester) by the degree of substitution and by the molar ratio (acetyl and phthaloyl groups).Purity:Min. 95%Fluorescein isothiocyanate-carboxymethyl-dextran - Average MW 4,000
