Cultrex® Basement Membrane Extract (BME) is a soluble form of basement membrane purified from Engelbreth-Holm-Swarm (EHS) tumor. This extract provides a natural extracellular matrix hydrogel that polymerizes at 37°C to form a reconstituted basement membrane. Basement membranes are continuous sheets of specialized extracellular matrix that form an interface between endothelial, epithelial, muscle, or neuronal cells and their adjacent stroma and that play an essential role in tissue organization by influencing cell adhesion, migration, proliferation, and differentiation. The major components of BME include laminin, collagen IV, entactin, and heparin sulfate proteoglycans.

Cultrex® 5X BME Solution is a Basement Membrane Matrix that has been developed, produced and qualified for the Cultrex® BME Cell Invasion Assays. Cultrex® 5X BME Solution is processed to reduce matrix-associated growth factors and provide a more defined model system.
