The present invention relates to a carrier for bio-related molecule immobilization, which comprises a resin substrate, an amino group-containing compound layer that is formed on the resin substrate, and a polyvalent carboxylic acid layer that is formed on the amino group-containing compound layer. The carboxyl groups in the polyvalent carboxylic acid layer are actively esterified; and the (COO peak intensity)/(C&#x2014;C peak intensity) ratio of the C1s spectrum is from 0.064 to 0.12 (inclusive) if the carrier surface before the active esterification is measured by X-ray photoelectron spectroscopy. The present invention also relates to a carrier for bio-related molecule immobilization, which comprises a water repellent resin substrate, an aminoalkyl silane layer that is formed on the resin substrate and a polyvalent carboxylic acid layer that is formed on the aminoalkyl silane layer, and which is characterized in that: the carboxyl groups in the polyvalent carboxylic acid layer are actively esterified; and the resin substrate is exposed after the formation of the aminoalkyl silane layer.

Carrier for bio-related molecule immobilization

A cell culture apparatus including cell culture units U and a measurement part (). The measurement part () is provided with an imaging part () and is disposed so as to be capable of moving up and down between a back panel part () of a casing () and a culture container accommodating shelf (). When the measurement unit () reaches a measurement position of each cell culture unit U which is a measurement subject, the culture container accommodating shelf () slides toward the measurement unit () so that portions to be measured of culture containers U, Uin each cell culture unit U come in an imaging range of the imaging part ().
