Immunohistochemical studies of the human cutaneous basement membrane-anchoring fibril complex

Antiserum to the human cutaneous basement membrane-anchoring fibril complex specifically binds to the basement membrane zone of normal human skin as demonstrated by indirect immunofluorescence and, in addition, cross-reacts with normal human glomerulus. This antiserum does not prevent binding of pemphigoid antibody to its specific antigen; thus the antigen of bullous pemphigoid is unlikely to be a component of the cutaneous basement membrane (basal lamina).
