Stable Epithalon compound for intracellular enzyme activity mechanism study

Epithalon (also known as Epitalon or Epithalone) is the synthetic version of the polypeptide Epithalamin which is naturally produced in humans. This pineal peptide preparation is secreted in the epithlamium-epiphyseal region of the brain. Its more prominent tasks are: to regulate metabolism in the epiphysis, increase the sensitivity of hypothalamus to its natural hormonal influences, normalize the function of the anterior pituitary, regulate the levels of gonadotropins and melatonin in the body. Epithalamin increases a person's resistance to emotional stress and also acts as an antioxidant.

Epithalon is a peptide used to regulate the cell cycle through up-regulation of telomerase activity. The sequence of amino acids in the peptide is Alanine-Glutamate-Asparagine-Glycine. Animal studies have been done on the effects of Epithalon on suppression of spontaneous mammary tumors and spontaneous carcinogenesis.

1. How to preserve peptides after receiving them?
Peptides in the form of lyophilized powder can be transported at room temperature by vacuum packaging, while polypeptides in the dissolved state need to be refrigerated at 2°C - 8°C. For long-term storage, peptides should be stored in the form of lyophilized powder stored at -20°C or -80°C in a sealed container with desiccant, which can avoid the degradation of peptides to the greatest extent.
 2. What is your lead time and shipping method?
Customized items are negotiable. 1-3 working day after payment arranges the shipping. Parcels shipping by sea, by air, or by express (EMS, UPS, DHL, TNT, FEDEX, etc).
