i've been performing the intratracheal instillation in mice with your methods. After instillation, the mouse starts coughing which may cause the inconsistent doses of LPS. how to avoid the coughing during the procedure???

There will always be some respiratory distress after an intratracheal liquid challenge--that cannot be avoided. I would keep the instillate volume to less than 50 microliters if at all possible. Also, deeper sedation usually helps blunt the coughing response.
