Vitronectin may be used for coating tissue culture surfaces to promote cell adhesion, proliferation and differentiation, or as an additive for serum-free media.

Human Vitronectin provides a functionally defined and effective feeder-free surface for the attachment and maintenance of embryonic stem cells in a pluripotent state. It is an extracellular, soluble, disulfide-linked dimer, composed of a 75 kDa and 65 kDA peptide chain with a total molecular weight of 140 kDa. Vitronectin is a major 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 may be used for coating tissue culture surfaces to promote cell adhesion, proliferation and differentiation, or as an additive for serum-free media.

Advantages:

• Rapid attachment
• High plating and cloning efficiencies
• Good proliferation, high saturation density
• Promotes attachment of H9 human embryonic stem cells
• Effectively maintains human embryonic stem cells in a pluripotent stage as evidenced by intracellular staining for the stem cell markers

Research Application:

• ELISA
• Immunoblotting
• Cell culture substratum
• Stem cell research
