Binding to cell surfaces by antibodies against exoATPase.

Avian oviductal secretions contain an exoATPase which has been purified up to 900-fold. Antibodies to this fraction bind to several cell types and to membrane fractions solubilized by selected detergents. The experiments indicate that a related antigen is present in plasma membranes and that exoATPase is released by a shedding process.
