Abstract
In order to realize micro enzyme-linked immunosorbent assay (ELISA) of a tumor marker carcinoembryonic antigen (CEA) from tissue cells, we developed a rapid cell disruption method using a Shirasu porous glass (SPG) filter integrated in a plastic microchip. CEA concentration in serum diluted sample solutions after the cell disruption was analyzed by a newly developed micro ELISA system. © 2006 Society for Chemistry and Micro-Nano Systems.
