In blood, oxytocin binds with big proteins. Acidification of blood is required to separate and purify oxytocin.
Oxytocin (OXT) is a mammalian neurohypophysial hormone. Produced by the hypothalamus and stored and secreted by the posterior pituitary gland. Oxytocin is a peptide of nine amino acids with the sequence of cys –tyr – Ile – gln – asn – cys – pro – leu – gly. The oxytocin peptide is synthesized as an inactive precursor protein from the OXT gene. Its actions are mediated by a G-protein coupled receptor that requires Mg2+ and cholesterol. It belongs to the rhodopsin-type group of G-protein-coupled receptors. Oxytocin plays an important role in the neuroanatomy of intimacy, specifically in sexual reproduction of both sexes, in particular during and after childbirth; It is released in large amounts after distension of the cervix and uterus during labor, facilitating birth, maternal bonding, and, after stimulation of the nipples, lactation.
The entire kit may be stored at -20°C for up to 1 year from the date of shipment. Avoid repeated freeze-thaw cycles. The kit may be stored at 4°C for up to 6 months. For extended storage, it is recommended to store at -80°C.
