Phylogenetic studies with pemphigus and pemphigoid antibodies

Abstract

Indirect immunofluorescence (IF) studies were performed on skin from a variety of vertebrate specimens and IgG fractions from pemphigoid and pemphigus sera. Pemphigoid antigen was present in fish, amphibian, reptilian, avian and mammalian skin, whereas pemphigus antigen was observed in avian and mammalian skin only.
