Cultrex 3-D Culture Matrix Laminin I Summary

Cultrex 3-D Culture Matrix Laminin I is an extracellular matrix hydrogel that directs cells to grow in three dimensions and assemble into organotypic structures in vitro.

Why Use Cultrex 3-D Culture Matrix Laminin I?

Cultrex 3-D Culture Matrix Laminin I is purified from Engelbreth-Holm-Swarm (EHS) tumor and is provided at a high concentration that is capable of polymerizing to form a hydrogel at 37°C. Laminin I is a major component of the basement membrane which is a continuous sheet of specialized extracellular matrix that forms an interface between endothelial, epithelial, muscle, or neuronal cells and their adjacent stroma and that plays an essential role in tissue organization by influencing cell adhesion, migration, proliferation, and differentiation. Cultrex 3-D Culture Matrix Laminin I is a purified basement membrane protein that has been developed, produced and qualified specifically for use in 3-D culture studies. Cultrex 3-D Culture Matrix Laminin I may also be used as to supplement customized hydrogel or medium formulations for cell culture.
