title: Secretory proteins of the lung in rodents: immunocytochemistry.
abstract: The reactivity of rabbit antisera to rat lung secretory proteins with other rodent species was evaluated by immunocytochemistry. Rabbit anti-rat surfactant apoprotein antiserum reacts with the cytoplasm of rat, mouse, and hamster type II pneumocytes and is specific for these cells. Rabbit antiserum to rat Clara cell secretory proteins stains rat, mouse, and hamster Clara cells. Rabbit antisera specific to the two antigenic types of rat Clara cell antigens were also both reactive with rat, mouse, and hamster Clara cells. An antiserum to the non-serum proteins of hamster lung lavage was also prepared and shown to be specifically reactive with hamster Clara cells. The availability of specific reagents for secretory proteins of rodent lungs is expected to facilitate studies of the respective cell types in various pathologic states.
