Ultrastructural localization of rat Clara cell 10 KD secretory protein by the immunogold technique using polyclonal and monoclonal antibodies.

Abstract

Using a monoclonal antibody and affinity-purified polyclonal antiserum against a 10 KD protein isolated from rat pulmonary lavage, we have localized the protein within Clara cells by a post-embedment protein A-gold technique. The gold particles were localized over the secretory granules of rat Clara cells. Ultrastructural immunolocalization was abolished when the primary antibodies were previously absorbed with purified 10 KD protein. Other pulmonary cells, including type II pneumocytes and ciliated cells, were negative with this technique. These results demonstrate the presence of the 10 KD protein in the secretory granules of the Clara cell and support the concept that this protein constitutes a specific and unique secretory product of Clara cells.
