A cell accommodating chip is adapted for use in a screening apparatus for searching for a predetermined cell based on optical information emitted from a substance on the cell accommodating chip and selectively collecting the cell searched for. The cell accommodating chip includes a substrate composed of a light-transmitting material, and a plurality of wells capable of accommodating cells, the plurality of wells being provided on at least one of main faces of the substrate. A surface of the cell accommodating chip having the plurality of wells is coated with a specific polymer having a crosslinked structure.

A sugar chain array containing a sugar chain immobilized thereon for detecting binding between an analyte and a sugar chain, and a sugar chain array having the sugar chain immobilized thereon that is capable of inhibiting non-specific adsorption and binding of an analyte without having to coat the array with an adsorption inhibitor. A specific sugar chain is immobilized on the array, and is useful for detecting binding between the sugar chain and an analyte, such as a pathogen of an infectious disease or an excretion thereof. In addition, in the array, when a base material is coated with a polymeric compound having a unit having a primary amino group, a unit for maintaining hydrophilicity, and a unit having a hydrophobic group, the sugar chain is immobilized efficiently and non-specific adsorption and binding of the analyte can be effectively inhibited.
