This method is most commonly used in biotechnology for immobilization of living cells in alginate gel. In contrast to most other polysaccharide gels, alginate gels can develop and set at constant temperature.

This kind of biofactory has been implanted into animals and diabetic patients, and has been seen to function for at least one year. The monomers can appear in homopolymeric blocks of consecutive G-residues G-blocksconsecutive M-residues M-blocksalternating M and G-residues MG-blocks or randomly organized blocks.

In vitro cell culture biopollymer mouse fibroblasts V79 Chinese hamster Alginate products: Viscosity measurements are often used as a simple measurable parameter of changes in the molar mass of a polymer, and thereby can be used as a stability indicating parameter. Consequently, the gel network will also be different. Hyaluronan Sodium hyaluronate, or hyaluronan, is a linear polymer composed of N-acetyl-glucosamine and glucuronic acid.

Single dose toxicity study by the intraperitoneal route Report number: Chitosan is bioadhesive and has the ability to transiently open tight junctions in the nasal epithelia, thereby permitting drugs to diffuse through this barrier. Effect of sodium alginate on cell survival of V and 3T3 cells cultured in vitro Report number: If you continue to use this site we will assume that you are happy with it. The biopolymers alginate, chitosan and hyaluronan are well known and have been used in many pharmaceutical formulations for many years.

Jump to page content Accessibility. Manufacture of biopolymers for use in drug delivery systems should be in accordance with current good manufacturing practice GMP guidelines.

Depolymerization of alginates will occur in solution and in the solid state due to a variety of mechanisms. One application of gelling of alginate is in the immobilisation or encapsulation of living cells in alginate gels to form artificial organs and cell therapy constructs.


These polysaccharides play a central role in the development of new drug delivery concepts. The main difference between internal and diffusion setting is the gelling kinetics.

Gels, pastes, fibers and solid structures of alginate are being evaluated for use in numerous tissue-engineering applications. The gelling process is highly dependent on diffusion of gelling ions into the polymer network and there are essentially two main classical methods for the preparation of alginate gels: In these gels, it is mostly the homopolymeric blocks that form the junctions, where the stability of the gel is determined by the relative content of G-blocks [7].

Alginate is a straight-chain polysaccharide composed of two monomers, mannuronic acid and its C-5 epimer guluronic acid.

Sterile Purchase the product. It is in commercial use or in advanced clinical evaluation in a range of pharmaceutical and biomedical applications, including bone regeneration and tissue bulking. New research shows that hyaluronan can bind to specific cellular receptors and act as a drug-targeting molecule.

FMC BioPolymer – Alginate, chitosan and hyaluronan in drug delivery

Last shipment date of orders are December 17th. Store NovaMatrix Manufacturing of industrial alginates since Pharmacokinetics of poly-M Report number: Chitosan is a linear biopolymer that consists of glucosamine and N-acetyl-glucosamine. Our products include ultrapure grades of sodium alginate and sodium hyaluronates that fulfill functional and regulatory requirements.

This unique property is particularly useful in applications involving fragile materials like cells or tissue with low tolerance for higher temperatures. We use cookies to ensure that we give you the best experience on our website. These may include, but not be limited to applications such as drug delivery, tissue engineering, cell encapsulation, and medical devices.


Alginate is one of the most versatile biopolymers.

G-blocks form stiff chain elements, and two G-blocks of more than 6 residues each form stable cross-linked junctions with divalent cations e. Aqueous solutions of alginates are viscous, the observed solution viscosity being dependent on molar mass, concentration of alginate, temperature, and potentially also presence of salts and other compounds in the formulation.

Gelling occurs when the divalent cations take part in the interchain ionic binding between guluronic acids blocks G-blocks in biopolymee polymer chain giving rise to a three dimensional network. The best known technology is immobilization of living cells in alginate gels.

December shutdown and Christmas Holidays: During storage, the lid of the container should be kept closed. Increased temperature will increase the rate of depolymerization for all mechanisms mentioned above Holme et al.


The gel is, however, not porous to antibodies or immune cells and can act as a continuous production system for substances such as insulin. If you continue to use this site we will assume that you are happy with it.

There are no mammalian enzymes that are active towards alginates, however, even in alginae, one must expect random depolymerization mechanisms like the ones described above to occur.

At low pH, protonized alginates will form acidic gels. Such binding zones between the G-blocks are often referred to as egg-boxes, and consequently alginates with a high content of G-blocks induce stronger gels.

In vivo data on the kinetics and mechanism of depolymerization of alginates are scarce.
