Summary Polyclonal antibodies against native human typeV collagen were produced in rabbits and goats. Following purification, crossreaction of the antibodies with highly immunogenic peptides of basement membranes or the interstitial matrix was excluded on the basis of sensitive radioimmunoassays. These antibodies, when applied to cryostat sections of human oral mucosa, liver and arterial walls, never stained basement membranes as did antibodies against type-IV collagen or laminin. On the contrary, we observed delicate arborizing fibers in the interstitial compartment with extensions contacting structures such as subepidermal basement membranes. Arterioles contained a unilamellar sheath of longitudinally oriented fibers limited to the intimal layer. Larger arteries exhibited a multilamellar fibrous fluorescence over the whole intima, whereas the media showed a much weaker staining. The data identified type-V collagen as an interstitial fibrillar collagen rather than a basement membrane collagen, with a tissue pattern completely different from that of collagens types I, III, VI or fibronectin. A reinterpretation of the role of type-V collagen in connective tissue function is warranted.
