Product Summary for Cultrex UltiMatrix Reduced Growth Factor Basement Membrane Extract
Why use Cultrex UltiMatrix RGF BME Matrix for Organoid and Pluripotent Stem Cell Culture?
Cultrex UltiMatrix Reduced Growth Factor (RGF) Basement Membrane Extract (BME) is a soluble form of basement membrane that provides high storage modulus, enhanced levels of entactin/nidogen, elevated protein concentration, and robust clarity and purity that ensures that the hydrogel contains the maximal amount of soluble extracellular matrix proteins. These compositional and concentration enhancements make Cultrex UltiMatrix RGF BME the choice hydrogel matrix with proven efficacy in organoid cell culture, induced pluripotent stem cell expansion and differentiation, spheroid formation, and other 2D and 3D cell culture applications.
Cultrex UltiMatrix RGF BME is purified from mouse Engelbreth-Holm-Swarm (EHS) tumor, Cultrex UltiMatrix RGF BME is viscous at 2-8 °C and gels at 37 °C to form a reconstituted basement membrane.

How Do I Use Cultrex UltiMatrix RGF BME?
Basement membrane matrix hydrogels play an essential role in developing complex in vitro and ex vivo cell and tissue culture models. By providing an optimized mixture of laminin, collagen IV, entactin/nidogen, and heparan sulfate proteoglycans, hydrogels like Cultrex UltiMatrix RGF BME provide native cell-matrix interactions that influence cell behavior and native developmental programs that promote complex cell culture and 3D tissue generation in vitro.
To preserve its performance benefits, Cultrex UltiMatrix RGF BME should be thawed overnight at 2-8 °C; the thawed hydrogel solidifies quickly at temperatures above 15 °C. When thawing, aliquoting, and diluting Cultrex UltiMatrix RGF BME, keep it on ice to prevent untimely gelling.

Scientific Data Images for Cultrex UltiMatrix Reduced Growth Factor Basement Membrane Extract
Figure 1. Goblet Cells in Adult Stem Cell-derived Human Descending Colon Organoids.
Adult stem cells isolated from human descending colon were embedded in Cultrex UltiMatrix RGF BME and cultured in growth medium for 30 days. Organoids were fixed and stained with MUC2 (green; Catalog # NBP2-44431), to visualize intestinal goblet cells, and counterstained for E-Cadherin (red; Catalog # AF748) and DAPI (blue; Catalog # 5748).
Figure 2. Cultrex UltiMatrix shows improved lot-to-lot consistency with low endotoxin and high protein concentration across 20 recent lots of Cultrex UltiMatrix.
The brown lines represents the endotoxin levels measured in 20 recent lots of Cultrex UltiMatrix. The graph shows consistently low levels of endotoxin across the lots. Cultrex UltiMatrix is specifically designed to maintain low endotoxin levels. The blue lines represents the protein concentration measured in the same 20 lots of Cultrex UltiMatrix. The graph demonstrates the consistency of protein concentration from lot to lot, highlighting the product's ability to maintain higher, constant protein levels. Cultrex UltiMatrix is designed to provide consistent protein concentration for reliable experimental outcomes.
Figure 3. Cultrex UltiMatrix RGF Basement Membrane Extract (BME) Displays Consistent Lot-to-Lot ECM Composition, High Tensile Strength, and Gel Rates.
A) Simple Western analysis for Entactin, Laminin, and Collagen IV across two lots of both Cultrex UltiMatrix RGF BME (Catalog # BME001) and an alternate commercial BME matrix. Cultrex UltiMatrix RGF BME shows consistent expression of Entactin, compared to the alternate ECM matrix. B) The tensile strength (elastic modulus) dynamics across two lots of Cultrex UltiMatrix RGF BME and an alternate commercial BME matrix. The elastic modulus was measured at increasing temperatures to determine tensile strength and gelling rate across two independent lots of Cultrex UltiMatrix RGF BME (Catalog # BME001) and the alternate BME matrix. Cultrex UltiMatrix RGF BME was found to display consistent gelling rates and high tensile strength (storage modulus) compared to the alternate commercial BME matrix.

Background: Basement Membrane Extracts
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.
