Patent ID: 11940442

Abstract:
The current technology is related to methods for rapidly determining the metabolic baseline and potential of living cells. Embodiments relate to measuring the activity of each of the two major energy-generating pathways within the cell: mitochondrial respiration and glycolysis, first under baseline conditions, and again after applying a stress to the cells to demand increased energy supply. In some embodiments the stress may be applied by exposing the cells to a combination of two chemical compounds: a mitochondrial uncoupler and an ATP synthase inhibitor. In one embodiment, the metabolic energy generating activity of the mitochondrial respiration pathway is determined by measuring the rate of oxygen consumption by the living cells, and the metabolic energy generating activity of the glycolysis pathway is determined from a measurement of extracellular acidification caused by secretion of protons from the cell. Other embodiments are related to an apparatus for determining a metabolic potential of a cell sample in a well of a multiwell plate.
