Dextran T2 (MW 2,000) can be used as a model substrate to characterize the catalytic properties of dextranase (such as optimal pH, temperature and product specificity), and to study enzymatic mechanism research and polysaccharide degradation pathways in glycobiology. The Dextran series of compounds are also a natural polysaccharide drug carrier, which can be connected to drugs through covalent bonding methods such as ester bonds, amide bonds or click chemistry, or self-assembled to form carriers such as nanoparticles and hydrogels. Dextran is biodegradable and biocompatible, and can achieve targeted delivery and controlled release of drugs. Dextran derivatives can prolong drug half-life, increase local concentration and reduce immune clearance activity.

Konjac glucomannan (Viscosity≥15000mPa.s) forms a defensive coating on the intestinal surface, reducing levels of blood glucose, cholesterol, triglycerides and blood pressure; it is specifically degraded by colonic β-mannanase produced by human colonic bacteria. Konjac glucomannan (Viscosity≥15000mPa.s) can be used as a food additive, dietary supplement and excipient for oral colon-targeted drug delivery systems. Konjac glucomannan (Viscosity≥15000mPa.s) is applicable to research related to various diseases such as type 2 diabetes, obesity, atopic dermatitis and metabolic syndrome, as well as research in fields including biotechnology, pharmaceuticals and tissue engineering.

Polydextrose is an orally active prebiotic. Polydextrose promotes the growth of Pediococcus pentosaceus ATCC 43200. Polydextrose reduces cholesterol and synergistically lowers blood sugar with Sitagliptin (HY-13749). Currently, it is mainly used in the research of diseases such as hyperlipidemia, type 2 diabetes, and postoperative iron deficiency anemia.

Starch (from potato) (Edible corn starch (from potato)) is a type of starch derived from potatoes. Starch (from potato) consists of amylose and amylopectin, and has properties such as easy gelatinization and high viscosity. Starch (from potato) is the main carbohydrate in potatoes and an important raw material for the food industry.

Chitosan (Deacetylated chitin; Poly(D-glucosamine)) (≥80% deacetylated, Medium viscosity,200-400mPa.s) is a polysaccharide obtained by deacetylating chitin, and exhibits antimicrobial activity against various bacteria and fungi.

Methyl cellulose (MC) (Viscosity:1500mPa.s) is a non-ionic cellulose ether with surface activity and thermogelation properties. Methyl cellulose (Viscosity:1500mPa.s) is widely used as drug delivery agents, thickeners, stabilizers, emulsifiers, etc., in industries such as pharmaceuticals, food, cosmetics, and construction.

Gellan gum is a linear microbial exopolysaccharide that can be used as a cell scaffold for both soft tissue and load bearing applications. Gellan gum has many advantages such as biocompatibility, biodegradability, nontoxic in nature, and physical stability in the presence of cations.

Starch soluble is a biodegradable, highly biocompatible hydrophilic biopolymer nanocarrier. Starch soluble forms complexes with iodine, acts on multiple bacterial targets, and improves the storage stability of iodine. Starch soluble enhances the solubility and dissolution rate of Gefitinib (HY-50895). Starch soluble can be used as a nanocarrier for relevant studies.

DEAE-Dextran (MW 40000) is a biochemical reagent that can be used as a biological material or organic compound for life science related research.

Chondroitin sulfate (from pig) (Chondroitin polysulfate (from pig)) is a sulfated linear polysaccharide extracted from pigs, which belongs to glycosaminoglycans. Chondroitin sulfate (from pig) exerts inconsistent inhibitory effects on the resorptive activity of human osteoclasts. Chondroitin sulfate (from pig) can be used in studies related to osteoarthritis.

Dextran sulfate, low sulfate (MW 40000), a biopolymer, is a sulfated polysaccharide.
