title: Immunoelectronmicroscopic localization of actin in ionophore-treated boar sperm.
abstract: Actin in ionophore-A23187 treated boar sperm has been localized by indirect immunofluorescence and immunoelectronmicroscopy (IEM), using an anti-actin monoclonal antibody. By IEM, after en bloc staining technique and treatment with 15 nm colloidal gold-IgM complex, actin was found associated with the plasma membrane (PM) and the outer acrosomal membrane vesicles and under the PM of the equatorial segment.
