  • Relevance

    Melatonin, the principal hormone of the pineal gland, is also produced by the retina, lens and GI tract. It is naturally synthesized from the amino acid tryptophan (via synthesis of serotonin) by the enzyme 5-hydroxyindole-O-methyltransferase. Production of melatonin by the pineal gland is under the influence of the suprachiasmatic nucleus of the hypothalamus (SCN -the site of a circadian clock) which receives information from the retina about the daily pattern of light and darkness. Melatonin can alter the timing of mammalian circadian rhythms, as well as regulate the reproductive alterations that occur in response to changes in day length in seasonally breeding mammals. Melatonin is also an extremely powerful antioxidant, with a particular role in the protection of nuclear and mitochondrial DNA. Therapeutically there may be many potential uses for melatonin such as in the treatment of various forms of some forms of depression, cancer, HIV, plus other viral diseases. Currently, Melatonin is a popular therapy for jet-lag and disturbances of sleep.

  • Goat anti-rabbit IgG was coated onto 96-wells. Serial dilutions of Melatonin (0, 3, 10, 30, 100, 300pg/mL) was added (25μL). This was followed by adding 50μL HRP-conjugated Melatonin and 4.0-4.5ng/mL of ab241066 (50μL) into each well. Plates were incubated for 2 hours at room temperature by shaking. After washing, 125μL of Tetramethylbenzidine (TMB) substrate was added and incubated for 30 minutes without shaking for color development. Then 125μL of stopping solution (acid solution) was dispensed and OD was read at 450 nm on a microplate reader within 5 minutes.
