Cultrex: Your Extracellular Matrix Solution
Cultrex BMEs are a mixture of specialized protein extract purified from the Engelbreth-Holm-Swarm (EHS) murine tumor. These extracts provide a natural extracellular matrix hydrogel that polymerizes at 37 °C to form a reconstituted basement membrane that is used to promote and maintain a differentiated phenotype of cell cultures such as epithelial cells, endothelial cells, glandular cells, neurons, and smooth muscle cells. BME can also be utilized in cell attachment, neurite outgrowth, angiogenesis, in vitro cell invasion and in vivo tumorigenicity assays.
Product Features
- Rapid - gels within 30 minutes at 37 °C.
- Reliable - maintains gelled form in culture medium for 14 days.
- Sterile - screened for bacteria, fungi, and mycoplasma.
- Specific - available with reduced growth factor content, with or without Phenol Red
Our most advanced extracellular matrix, Cultrex UltiMatrix RGF BME, is specially formulated with higher extracellular protein content, consistency, and clarity for optimal organoid, spheroid, and pluripotent stem cell culture.
Cultrex Basement Membrane Extracts
Cultrex BME Matrices for 2-D and 3-D culture are offered in multiple formats to support application-specific needs. Cultrex Reduced Growth Factor (RGF) BME, which is processed to reduce matrix-associated growth factors, is ideal for research that requires a more defined model system. Cultrex UltiMatrix, as our most advanced matrix, is recommended for all below applications since its enhanced composition and consistency can benefit many types of cultures.
For additional guidance on matrix selection and protocols for use, including handling tips, see the Cultrex ECM Selection and Use Guide.

Cultrex ECM Proteins Portfolio
Cultrex ECM Proteins provide a defined substrate for cell adhesion in culture. Many proteins of the ECM interact with cells via cell surface integrin family receptors. The resulting focal contacts are important for the maintenance of tissue architecture and for supporting a variety of cellular processes. ECM molecule/integrin binding may initiate a complex network of signal transduction cascades that, depending on the context, play an important role in cell spreading, migration, proliferation, and differentiation during embryogenesis, wound healing, and tumor development. To accommodate a variety of different models, we have developed a full range of ECM component proteins including Laminin I, Collagen I, Collagen IV, and Vitronectin. These include purified proteins that have been qualified for 3-D or stem cell cultures.
Cell Matrices Best Practices
| Name | Description | Catalog # |
|---|---|---|
| Mouse Laminin I | A purified basement membrane protein that has been developed, produced and qualified specifically for cell culture studies where the presence of pathogens may cause concern. | View All |
| Mouse Collagen IV | Used for coating of tissue culture surfaces to promote cell attachment and proliferation and to study its effects on cell behavior. | View All |
| Rat Collagen I | Major structural component of extracellular matrices found in connective tissue and internal organs, used to promote cell attachment, growth, differentiation, migration, and tissue morphogenesis during development. The 5 mg/ml concentration is very viscous for researchers wanting a thicker Collagen. | View All |
| Rat Collagen I, Lower Viscosity | Diluted to a lower concentration (3 mg/ml); it is less viscous and easier to handle. A major structural component of extracellular matrices found in connective tissue and internal organs, but is most prevalent in dermis, tendons, and bone. It promotes cell attachment, proliferation, differentiation, migration, and tissue morphogenesis. | View All |
