Abstract: 

Measurement of cellular tracer uptake is widely applied to understand the physiological status of cells and their interactions with imaging agents and pharmaceuticals. In-culture measurements have the advantage of less stress to cells. However, the tracer solution still needs to be loaded, unloaded and purged from the cell culture during the measurements. Here, we propose a continuously infused microfluidic radioassay (CIMR) system for continuous in-culture measurement of cellular uptake. The system was tested to investigate the influence of glucose concentration in cell culture medium on the 2-deoxy-2-(18F)fluoro-D-glucose (18F-FDG) uptake kinetics.
