Arg1 immunostaining in lung sections of wild-type mice. Arg1 immunoreactivity in lungs of mice after saline (a) or endotoxin challenge (b). Immunoenzyme stainings were performed on paraffin-embedded sections using polyclonal rabbit anti-Arg1 and counterstained with hematoxylin. Representative image shows Arg1 immunoreactive protein (purple-brown) in bronchial epithelium (BR), connective tissue (CT) and small pulmonary arteries (PA)
