APPARATUS FOR TREATING SAMPLE IN MICROAMOUNT

摘要

It is intended to provide a constitution for, in pouring a sample in a microamount into cells, preventing the transfer of the sample into other cells or the overflow of the sample; a constitution whereby the position of the poured sample can be controlled in the wells or the sample can be transferred into the subsequent wells under controlling; and an apparatus for detecting cell chemotaxis and separating chemotactic cells by using these constitutions. Namely, an apparatus for treating a sample in a microamount characterized in that, in case where a plural number of wells are connected to each other via members resistant to a fluid and each well is provided with tubes for pouring and sucking off the sample optionally together with a tube for relieving a pressure change in the pouring/sucking off step, these tubes have a space in common, in which a liquid can be contained, at the upper ends thereof. This apparatus is used for detecting cell chemotaxis and separating chemotactic cells.
