title: [Immunochemical and physico-chemical characteristics of lactoferrin in human body fluids].
abstract: It is proved that lactoferrins of different human body fluids (sperm, saliva, milk, tears, urine, bile, sweat, liquor, lymph, blood serum) are immunochemically identical. The lactoferrin is purified from milk, saliva and sperm and the identity of physical and chemical properties of lactoferrins of various origins is proved. The quantitative estimation of the contents of this protein in normal body fluids is given. It is detected the dependence of this protein' electrophoretic mobility and isoelectric point of degree of iron saturation. It is found that lactoferrin is capable to form complexes with esterase.
