1. The zinc content of rat spermatozoa increases, upon ejaculation, from 0.035 to 1.055 micrograms/10(6) cells. 2. The rat seminal plasma holds zinc both as free ion and as protein-bound forms. 3. Zinc-free ions bind in vitro to rat epididymal spermatozoa. 4. Zinc-protein complexes can be isolated, by a chromatographic procedure, from the dorsolateral lobe of rat prostate. 5.

Abstract
1. The zinc content of rat spermatozoa increases, upon ejaculation, from 0.035 to 1.055 micrograms/10(6) cells. 2. The rat seminal plasma holds zinc both as free ion and as protein-bound forms. 3. Zinc-free ions bind in vitro to rat epididymal spermatozoa. 4. Zinc-protein complexes can be isolated, by a chromatographic procedure, from the dorsolateral lobe of rat prostate. 5. The isolated zinc-protein complexes bind in vitro to rat epididymal spermatozoa.File in questo prodotto:
