Corning PureCoat cultureware is coated with biologically active, synthetic, animal-free peptides that are covalently linked to a proprietary surface to provide a highly consistent, cost-effective alternative to self-coated extracellular peptides. The proprietary covalent linkage orients the peptides for optimal binding and signaling.
