A monoclonal antibody which identifies an epitope in eccrine duct and acrosyringium.

A mouse monoclonal antibody obtained after immunization of BALB/c mice with large molecular weight salivary mucins decorated an epitope in eccrine duct and acrosyringium in sections from formalin-fixed, paraffin-embedded tissues. Eccrine coil, apocrine gland and other cutaneous structures were not decorated by the monoclonal antibody. This antibody was used to study the histogenesis of a number of adnexal neoplasms.
