Matrixome is a company name (and product brand) focused on cell culture reagents. Founded in 2015, the major shareholder is Nippi, Inc. (Japan). As implied by the Matrixome company name, the products are primarily proteins or biomaterials that provide scaffolding for mammalian cells to adhere to culture plates for various applications. The main products of Matrixome are proteolytic derivatives of human laminin that interact with integrin-protein subtypes which are transmembrane proteins on the surface of human cells (www.matrixome.co.jp/en/about/background). The iMatrix-511 protein is a very popular and effective surface matrix for cultivation of induced pluripotent stem cells.
