Antigenicity of the guinea pig's tympanic membrane

The immunogenicity of the middle ear constituents is a matter of prime importance. In this work, the authors were interested in the antigenicity of the guinea pig's tymphanic membrane. They reached the conclusion, after developing an antiserum (IgG), that the tympanic membrane of the guinea pig can be antigenic in the rabbit. After purification and absorption, a cross-reactivity remains between the tympanic membrane and the mucosae of the upper respiratory system.
