Clone VI F11 is useful for staining rat and human surfactant protein D . Antigen Distribution on Tissues and Cells: Alveolar type II cells, alveolar macrophages, two types of Clara cells SP-A+ and SP-A-, and extracellular deposits. Alveolar type III cells stain negative. No reaction on Rat skin, colon, kidney and liver.

Surfactant protein D is a Ca2+ -dependent carbohydrate binding protein with a similar structure as other C-type mammalian lectins such as conglutinin and SP-A. The molecular weight is 620 kD under non reducing conditions and 43 kD under reducing conditions. The function of SP-D is not clearly defined. SP-D enhances the production of oxygen radicals in alveolar macrophages and regulates some actions of SP-A, which is the most abundant surfactant protein. SP-D is synthesized and secreted by alveolar epithelial type II cells.Synonyms: COLEC7, Collectin-7, Lung surfactant protein D, PSP-D, PSPD, Pulmonary surfactant-associated protein D, SFTP4, SP-D
