title: The isolation and characterization of lactoferrin from sow milk and boar seminal plasma.
abstract: Lactoferrin isolated from sow milk (about 0-6 mg/ml) was shown to be chromatographically homogeneous, an observation supported by electrophoresis and by reaction against monospecific anti-lactoferrin antiserum. Isoelectric focusing showed multiple forms of the protein (i.e.p., 9-3 to 10-0) converted by neuraminidase to one form (i.e.p., 9-65). Boar seminal plasma contains immunologically identical lactoferrin (0-1 to 0-5 mg/ml) which binds strongly to boar spermatozoa.
