Basement membrane extract (BME) is a type of extracellular matrix (ECM) derived from Engelbreth-Holm-Swarm mouse sarcomas. BME is commonly used in cell culture and tissue engineering to provide a 2-D or 3-D scaffold for cells, allowing them to grow, differentiate, and interact in an environment that closely mimics the native ECM. This makes BME invaluable for modeling the behavior of cells in vivo. All Cultrex BME formulations are rigorously tested to ensure performance, quality, and lot-to-lot consistency.

Product Summary for Cultrex Reduced Growth Factor Basement Membrane Extract, Type R1
Why Use Cultrex RGF BME, Type R1?
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. Cultrex BME Type R1 provides a proprietary formulation that has a higher storage modulus when compared to our other products Cultrex BME, Cultrex BME Type 2 and Cultrex BME Type 3. Our new Cultrex BME Type R1 has a higher concentration of entactin, one of the BME components that connects laminins and collagens reinforcing the hydrogel structure. Cultrex BME Type R1 has been specifically designed to culture tissue organoids.
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.
