Summary for Cultrex Stem Cell Qualified Laminin I, Pathclear
Why Use Cultrex Stem Cell Qualified Laminin I?
Cultrex Mouse Laminin I is purified from Engelbreth-Holm-Swarm (EHS) tumor. Laminin I is a major component of the basement membrane which is a continuous sheet of specialized extracellular matrix that forms an interface between endothelial, epithelial, muscle, or neuronal cells and their adjacent stroma and that plays an essential role in tissue organization by influencing cell adhesion, migration, proliferation, and differentiation. This highly purified preparation of mouse Laminin I is composed of α1β1γ1 chains with a total molecular weight (MW) of 800 KDa.
Negative for the presence of bacteria and fungi.
