Data for: Mouse aversion to isoflurane anesthesia using the drop method

We assessed mouse aversion to isoflurane administered with the drop method at low concentrations, using a light-dark conditioned place aversion (CPA) paradigm. Latency to enter and the duration spent in the dark (+ isoflurane) chamber was recorded and used to calculate a CPA score based on initial and final preference tests. Our results indicate that using the drop method, to administer isoflurane concentrations between 1.7 and 2.7%, can be used to refine current rodent euthanasia methods.
