Application

Low endotoxin alginate solution is a 2 % low endotoxin alginate solution in DPBS buffer. It is sterile filtrated through 0.2 μm sterile filter, and ready to be used in biomedical applications.
Alginate is an anionic polysaccharide that is widely used in pharmaceutical and biomedical applications due to its non-animal origin, low toxicity, biocompatibility, and biodegradability. Alginate hydrogels are commonly used to fabricate tissue engineering scaffolds, bioinks for 3D bioprinting, and nanocarriers for drug & gene delivery. Alginate is commonly crosslinked into a hydrogel via ionic-crosslinking with divalent cations (e.g., Ca2+).
