Select an Option to See Pricing

Cultrex® BME Type 3 is a Basement Membrane Matrix that has been developed, produced and qualified specifically for use in in vivo studies. BME Type 3 is an extracellular matrix hydrogel that helps cells to adapt to in vivo transplantation. BME Type 3 mimics the in vivo microenvironment, including low glucose and low pH, to improve take rate and growth of implanted cells for xenograft and tumorgraft models.

Available Size(s): 1 ml, 2 x 5 ml, 5 ml Catalog Number: 3632-001-02 Categories: , Tags: ,


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 heparan sulfate proteoglycans.

Cultrex® BME Type 3 is physiologically aligned with the in vivo environment and is recommended for xenografts, tumorgrafts, and other in vivo applications.

Quality control specifications:
