The presence and localization of high molecular weight microtubule-associated proteins of the MAP 1 class in ciliated cells of porcine and rat respiratory tract was studied by immunoblotting and immunoelectron microscopy. Ciliary shafts of the porcine tracheal epithelium were isolated using a method that minimizes contamination of the preparation by other cellular fragments and fat. Immunoblotting with rabbit antibodies to bulk MAP 1 from hog brain clearly revealed the presence of anti-MAP 1-immunoreactive high molecular weight proteins of the MAP 1 size in these preparations. To localize MAP 1 proteins at the ultrastructural level, rat and porcine tracheal epithelia were embedded in LR White and subjected to immunogold electron microscopy. Anti-MAP 1-immunoreactive material was found at ciliary shafts and basal bodies, but not at basal feet or ciliary rootlets. Interestingly, the necklace region between the shaft and the basal body of the cilium was hardly reactive with anti-MAP 1 antibodies. This may indicate a reduced stability of ciliary microtubules in this region and could be an explanation why ciliary shafts in general break more easily there than elsewhere.
