Two esterases common to seminal plasma, other external secretions and leucocytes in man.
Two esterases previously identified in seminal plasma, on the basis of their electrophoretic mobility, immunogenicity and sensitivity to organophosphorus esters were detected in various human external secretions and leucocyte extracts. alpha-Esterase was found to be abundant in urine and milk whereas this enzyme occurred in a low concentration in seminal plasma, leucocyte extract, cervical  mucus and sweat. The concentration of betagamma-esterase was high in seminal plasma and leucocyte extract. The enzyme was present in small amounts in urine, milk, gastric juice, saliva, sputum, tears, cervical mucus and sweat.
