Naphthalene (Sigma Adrich #84679) was dissolved in corn oil at a concentration of 20 mg/mL at room temperature and sterile filtered before administration. C57Bl/6J or CCSP-CreER+/−; R26-LSL-YFP/iDTR mice were injected intraperitoneally with Naphthalene at 200 mg/kg body weight or an equivalent volume of corn oil for control animals. Mice were then monitored for signs of distress throughout recovery until sacrificed with anesthetic overdose at indicated timepoints.
