(A) UPE images from live mice (top row, N = 4) and recently euthanized mice (bottom row, N = 4) following 30 min of dark acclimation and a 60 min biophoton imaging session. (B) Graph showing total photon flux (photons/s) in live versus recently euthanized mice. Total flux was quantified using a whole-body ROI from the mice in panel A. (∗) Welch’s test (heteroscedastic t test), with p < 0.05. The bodies of both living and deceased mice in the experiments were at 37 °C.",
