Method and device for measuring multiple physiological properties of cells
First Claim
1. A method of determining a cell constituent extracted from or secreted into a volume of media disposed in a well by a sample comprising cells, the method comprising the steps of:
- (a) placing in an apparatus a multiwell plate comprising a plurality of said wells, at least one well containing said sample in an original volume of media, the apparatus comprising;
a plurality of moveable barriers that reduce a volume of the media in contact with the samples in the wells; and
sensors disposed on respective surfaces of said barriers in sensing contact with media in said wells,each barrier and respective sensor disposed on the surface thereof being configured for insertion into a respective well of the multiwell plate;
(b) moving the barriers and sensors into the wells to reduce the volume of the media about the cells in at least one well, defining a reduced-volume sample chamber in contact with the sample;
(c) analyzing with the respective sensor the cell constituent in the media in the reduced-volume sample chamber; and
(d) thereafter, moving the barriers to increase the reduced volume of media about the cells to substantially the original volume.

Abstract
A method of analyzing cells disposed in media within a vessel includes the steps of providing a vessel having an original volume of media about the cells, reducing the original volume of media about at least a portion of the cells to define a reduced volume of media, and analyzing a constituent related to the cells within the reduced volume of media. An apparatus for analyzing cells includes a stage adapted to receive a vessel holding cells and a volume of media, a plunger adapted to receive a barrier to create a reduced volume of media within the vessel including at least a portion of the cells, the barrier adapted for insertion into the vessel by relative movement of the stage and the plunger, and a sensor in sensing communication with the reduced volume of media, wherein the sensor is configured to analyze a constituent disposed within the reduced volume.
