MICROCHAMBER CHIP FOR CELL SPREADING

摘要

Provided is a micro chamber chip for cell expansion, with which the non-specific adsorption of cells onto a surface other than a micro chamber can be suppressed, and a rare cell from a substance that contains a large quantity of cells, such as a blood, can be stored, held and observed without a leakage of the rare cell. A micro chamber chip for cell expansion is provided with a micro chamber chip (20) in which a micro chamber (30) configured to store and hold one or more cells is formed on an upper surface (11) of a substrate (10), wherein an upper surface (11) of the micro chamber chip (20) and an inner wall surface (31) of the micro chamber (30) are coated with a blocking agent (50) that can suppress a non-specific adsorption of a cell on the upper surface (11).
