We are starting a urethane-induced lung cancer model in mice (sigma U2500) and are wondering if we need to prepare urethane solution the day of the injection or if urethane solution (100mg/mL) in PBS is stable? if stable, how long and what is the storage temperature?
The only info I found on internet is poly-urethane-related and my chemisitry sucks...
thanks in advance for your replies.
sincerely
