R-OR-393 poly(l-arginine)-β-cyclodextrin poly(l-arginine)-β-cyclodextrin poly(l-arginine)-β-cyclodextrin from ruixi Beta cyclodextrin, white crystal or crystalline powder. Beta cyclodextrin has a unique hollow molecular structure, which is hydrophilic on the outside and hydrophobic on the inside. Under the action of van der Waals force, the molecules of other substances can be absorbed into the molecular cavity, thus forming a inclusion complex like a molecular capsule. This characteristic of beta cyclodextrin has a very wide range of functions. price>
R-OR-394 dextran-poly-L-arginine dextran-poly-L-arginine dextran-poly-L-arginine from ruixi Arginine is a basic amino acid, which can be widely involved in the metabolism of body tissues, and is closely related to immune function, protein metabolism and wound healing. It can also promote blood ammonia to enter the urea cycle and prevent ammonia poisoning. Polyamine, the intermediate product of metabolism, is an important gastrointestinal mucosal protective agent and can promote mucosal proliferation. price>

It is a kind of natural polysaccharide extracted from brown algae or bacteria. Sodium alginate is a kind of polyanionic electrolyte. The molecular chain contains carboxylic acid and hydroxyl group. price>
R-OR-396 chitosan-poly-L-arginine PLLA2K-CS20K,PLA-Chitosan,chitosan-poly-L-arginine chitosan-poly-L-arginine from ruixi Polyarginine is a promising gene carrier. Through further modification of polyarginine, a series of gene vectors based on polyarginine were obtained, which not only improved the efficiency of gene transfer, but also reduced the cytotoxicity. price>
R-OR-397 PBLG-b-PGly polybenzyl-L-glutamate-b-Polyglycine PBLG-b-PGly from ruixi Polyglycine is a substance used to modify carbon fiber microelectrode differential pulse voltammetry for the determination of uric acid. In nature, polyglycine mainly exists in the fibroin of silk in the form of β - folded sheet. In the fibroin, it is antiparallel with other non polyglycine chains (peptides). price>
R-OR-398 PEG-Poly-L-leucine-poly(l-glutamic acid) Polyethylene glycol-Poly-L-leucine-poly(l-glutamic acid),PEG-Poly-L-leucine-poly(l-glutamic acid) from ruixi.Polyglutamic acid (γ - PGA), also known as natto gum and polyglutamic acid, is a kind of water-soluble, biodegradable, non-toxic biopolymer produced by microbial fermentation. Adding γ - PGA to cosmetics or maintenance products can effectively increase the skin of moisturizing ability and promote skin health. price>
