High affinity [125I]-iodomelatonin (17 pM) binding showed by autoradiography in blastocysts. Autoradiograms of the total (a), non-specific (30000 nM melatonin presence) (b), and specific (c) [125I]-iodomelatonin (17 pM) binding in seven days old bovine embryos that were produced without melatonin inclusion in oocyte maturation protocol. The autoradiograms are actual size (240 μm, embryo diameter).
