Cultrex Reduced Growth Factor Basement Membrane Extract, Type R1 Summary

Cultrex Reduced Growth Factor Basement Membrane Extract (RGF BME), Type R1 is an extracellular matrix hydrogel that is designed for the establishment and expansion of difficult grow organoid cultures. RGF BME Type R1 mimics the in vivo microenvironment and is enriched in entactin to improve take rate and growth of difficult to culture organoid progenitor cells.

Key Benefits

• Qualified for use in organoid cell culture
• Improves take-rate and growth in difficult organoid systems
• Rich in Entactin
• Quality controlled for peformance consistency

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 higher tensile strength 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.
