Identification of the epitopes on human type VII collagen for monoclonal antibodies LH 7.2 and clone I, 185.
Type VII collagen is the major component of anchoring fibrils, structures in human skin that mediate the adherence of the epidermis to the underlying dermis. Dystrophic forms of epidermolysis bullosa, a group of inherited mechanobullous disorders of the skin, are linked to the type VII collagen gene. Several mutations in the recessive form of this inherited disorder have been delineated. In this study, we mapped the epitopes of two commercially available monoclonal antibodies (clone I, 185 and LH 7.2) within the amino-terminal, non-collagenous domain of type VII (anchoring fibril) collagen. The precise localizations of the epitopes for these two monoclonal antibodies which are widely used to diagnose dystrophic epidermolysis bullosa, will be useful for the confirmation of gene mutations at the protein level.
