Biopolymer Characterization



Biopolymers are naturally occurring polymers like proteins and peptides, nucleic acids, polysaccharides (starch, cellulose, glycogen), lipids, and several other classes of molecules. In nature, they play an important role in cellular construction, storage of energy, or conservation and transmission of (genetic) information. 

Separation and Molecular Characterization of biopolymers are demanding scientific challenges. Wyatt Technology instruments provide the most advanced tools which enable you to successfully design and conduct your studies:
