An instant cell recognition system using a microfabricated coordinate standard chip useful for combinable cell observation with multiple microscopic apparatuses.

Disposable coordinate standard (CS) chips were fabricated by the ejection of melted polystyrene into a metal mold. The CS chip surface was divided into four parts different in height and width. The edge lines of these parts could be recognized as straight lines 2 mum in width in the microscope view and used as the X and Y axes for the culture dish.
