Cultrexes are the best 3D matrixes for cell cultures known as matrigel or cultrex. Basal membrane extracts higher the differentiation capacity or from basal membrane over what can be achieved by 2D monolayer cultures from epithelial cells. You can use cultrex for high differentiation in a 3D matrix as Basement Membrane Extracts (BME), extracellular matrix from lumen epithelial or endothelial cells. BME, collagen I, collagen IV, laminin I, fibronectin and vitronectin are pathogen tested and suitable for 3d and pluripotent stem cell culture. Cultrex Basement Membrane and the PathClear Protocol is supplied in a liquid form of basement membrane purified from Engelbreth-Holm-Swarm (EHS) tumor at a concentration of 13 - 17 mg/ml from Murine Engelbreth-Holm-Swarm (EHS) tumor with Dulbecco’s Modified Eagle’s medium without phenol red and with 11 ug/ml gentamicin sulfate with cultrex BME for thin Layer Method (non-gelling).
