Structural Proteins

Structural proteins are the most abundant class of proteins in nature. Collagen is recognized as the most abundant mammalian protein. Structural proteins such as collagen, fibronectin and laminin are utilized in cell culture applications as attachment factors. Sigma® offers the most comprehensive collection of structural proteins for extracellular matrix and cytoskeletal research as well as tools for cell culture and material science applications.
