PRONOVA® UltraPure (UP) alginates are biopolymers available as sodium salts. Alginates have the capabilities to form hydrogels, which make them particulary interesting for applications like tissue engineering, drug delivery and cell culture as they provide a protective 3D matrix for optimal cell growth. PRONOVA® UP VLVG is very low viscosity with high-G content, leading to the formation of stronger gels.
