NOF supplies a Biocompatible Anchor for cell Membrane (BAM), which would not injure the cells. BAM contains both oleyl groups as a hydrophobic cell membrane anchor and polyethylene glycol (PEG), which elevates the hydrophilicity, while its chemical structure is so designed as to have various reactive groups at the terminals of the PEG chain allowing them to bind them to physiologically active substances or surfaces of materials. Employment of BAM enables researchers to modify the surfaces of cells and tissues with physiologically active substances, such as proteins or drugs without injuring cells and tissues, and also to immobilize live cells and tissues on the surfaces of various kinds of materials. Since BAM exerts excellent functions beyond conventional concepts, it can be extensively used in the fields of pharmaceuticals and cosmetics.
