Why Use Cultrex Human Vitronectin?

Cultrex Human Vitronectin, Pathclear is purified from human plasma and is Pathclear certified to be free of common pathogens. Vitronectin is an extracellular, soluble, disulfide-linked dimer, composed of a 75 kDa and a 65 kDa peptide chain with a total molecular weight of 140 kDa. Vitronectin is a major plasma glycoprotein that promotes cellular adhesion and spreading. It also inhibits the membrane damaging effect of the terminal cytolytic complement pathway and binds to several serpin serine protease inhibitors. Vitronectin, along with collagen IV, fibronectin, and laminin can support robust, long term proliferation of undifferentiated human embryonic stem cells. Vitronectin can be used for coating tissue culture surfaces to promote cell adhesion, proliferation and differentiation, or as an additive for serum-free media. Vitronectin is purified from human plasma and is 0.2 μm sterile filtered. Cultrex Human Vitronectin is an extracellular matrix coating solution that provides a functionally defined and effective feeder-free surface for the attachment and maintenance of embryonic stem cells in a pluripotent state. It may also be used to supplement customized medium formulations for cell culture.
