More Information
Summary:Methods, systems, and kits for determining a level of dissolved oxygen within a microfluidic device are provided. The microfluidic device can be suitable for cell culture. The methods, systems, and kits can further be used to determine a level of oxygen consumption in a population of biological micro-objects. In particular, the methods, systems, and kits of the present disclosure rely on flowing a fluidic medium containing a dye and a supplied partial pressure of oxygen into the microfluidic device for a period of time, wherein fluorescence emitted by the dye changes based on availability of oxygen proximate to the dye; taking a fluorescence image of an area of interest within the chamber; and correlating fluorescence of the fluorescence image of the area of interest to a reference to determine an observed partial pressure of the oxygen in the area of interest.
