Abstract: Disclosed herein is a protein-based, genetically-encoded bioluminescent sensor that can report changes in intracellular ATP in live cells. This sensor is built from the NanoLuc luciferase (Promega) and mScarlet red fluorescent protein (DOI: 10.1038/nmeth.4074) in a novel platform that provides a much more quantitative optical signal for measurements. Analytical Chemistry demonstrates its characterization and that it can be used to image ATP differences in live cells under the skin of mice. This new sensor can be very useful for research purposes in cancer biology to measure cell health and chemotherapeutic drug efficacy for example in animal models of tumors or in cell-based screening.

Abstract: Disclosed is a fire evacuation installation. When evacuees are not able to evacuate through an emergency exit or other means of evacuation when a fire occurs, the fire evacuation installation may safely protect the evacuees from flames and poisonous gas until rescue workers arrive. Further, the fire evacuation installation may be prevented from being damaged by exposure to rain, and the fire evacuation installation may have an elegant outer appearance and be more easily installed. In addition, the fire evacuation installation may be selectively moved between the floors of a building.
