Immunohistochemical localization of nicotinic receptor subtypes in 134-day fetal monkey lung. (a) Anti-α1,3,5 (MAB 210) showing staining in alveolar macrophage. ×400. (b) Anti-α1,3,5 (MAB 210) showing staining in a subset of cells lining developing alveoli. ×1,000. Procedure as described in the research plan: AEC was used as immunoperoxidase substrate, and hematoxylin was used as counterstain. Arrows point to immunostained cells.
