Sodium alginate

Sodium alginate is the sodium salt of alginic acid, a natural polysaccharide found in brown algae. It is generally used as a stabilizer and thickener in the food industry. Sodium alginate may undergo cross-linking in the presence of divalent cations such as Ca2+ to form biodegradable stable gels, which finds applications as a material for cell encapsulation and immobilization.

PRODUCT FEATURES
Sodium alginate is a naturally derived biomaterial that can be chemically crosslinked with calcium chloride to create cell-laden hydrogels. These reagents are used in a variety of applications including bioprinting. The recommended preparation yields a streamlined matrix bioink that supports 3D printed cell-laden constructs.
Soluble in common solvents (THF, Chloroform, diH20). Upgraded thermal stability (very stable until 250°C). Rapid crystallization from melt and proper processing with thermoplastic techniques (T > 100°C). They may content bismuth residues but in vitro compatibility studies demonstrated that these materials are not cytotoxic and provide a valid substrate for cells to attach and proliferate.
