Immunofluorescent co-staining of CHI3L1 and F4/80 in the lung of CCSP-rtTA/(TetO)7-CMV-Stat3C mice.

CCSP-rtTA/(TetO)7-CMV-Stat3C bitransgenic mice were treated (+DOX) or untreated (-DOX) with doxycycline. Immunofluorescent staining of lung sections was performed using anti-CHI3L1 and F4/80 antibodies. Co-localization of both staining was observed in the merged picture. Bar represents 20 µm.
