An improved technique for the study of immunofluorescence using non-decalcified frozen guinea pig cochlea.

A technique for producing frozen sections from the non-decalcified guinea pig cochlea is described. The sections can be utilised for various immunofluorescent studies, including the detection of humoral antibodies against different cellular elements in patients with cochleo-vestibular disorders. The technique assures the preservation of the cochlear architecture and the tissue antigenicity, and it avoids damage to the fine cochlear structural details.
