title: Zinc binding properties of human prostatic tissue, prostatic secretion and seminal fluid.
abstract: When studied by gel filtration, zinc in prostatic cytosol (10(5) g, 1 h) was associated with high (greater than 80000), medium (3000-80000) and low molecular weight (less than 3000) molecules in approximately equal proportions. The molecules of high and medium Mr were not secreted into the prostatic fluid where all the zinc was associated with molecules of low Mr (probably citric acid). After ejaculation much of the zinc is redistributed and becomes bound to molecules of high and medium Mr of vesicular origin.
