title: Isolation and immunochemical localization of collagenase in mouse peritoneal macrophages.
abstract: Collagenase was isolated from the culture medium of thioglycollate-stimulated mouse peritoneal exudate macrophages. The macrophage collagenase activity was inhibited by goat anti-mouse bone collagenase antibody, indicating that macrophage collagenase immunologically cross-reacts with mouse bone collagenase. The enzyme was localized in mouse peritoneal macrophages by indirect immunofluorescent antibody technique. Distinct granular fluorescence was observed intracellularly in most thioglycollate-stimulated macrophages, whereas slight or no fluorescence was observed in non-stimulated control macrophages.
