title: Antitubular basement membrane autoantibody in a dog with chronic tubulointerstitial nephritis.
abstract: Linear deposition of immunoglobulin G was seen by direct immunofluorescence along the tubular basement membranes in the kidney of a dog with chronic tubulointerstitial nephritis. Autoantibody eluted from the affected kidney bound to the tubular basement membrane of normal canine kidney, but not to several other normal canine basement membranes. The pathogenic significance of the autoantibody in this dog was not determined.
