In the literature
Oxytocin is a cyclic nonapeptide closed by a single disulfide bridge between residues 1 and 6, supplied as a lyophilized powder in a sealed vial.
Oxytocin is one of the most documented nonapeptides in the neuroendocrine literature, studied in receptor-binding and cellular models since its synthesis by du Vigneaud in 1953.

About OXpeptides
Who we are
OX RESEARCH LTD operates OXpeptides. Company number 17464288 (England and Wales). We supply lyophilized research peptides in sealed glass vials, and one laboratory diluent, to researchers and laboratories.
How we work
Each production lot is sent to an independent third-party laboratory for HPLC purity and mass-spectrometry identity confirmation. The certificate is published on the product page with its lot number and its date as soon as the laboratory returns it; a lot still at the laboratory says so, in those words, rather than borrowing the figures of another lot. Every vial is crimp-sealed and carries the compound name, the net quantity in milligrams and the lot number. Orders ship from the warehouse that serves the delivery address, tracked.
Who we sell to
Research use only. Not for human or veterinary use. In practice that means three things we do not do: we publish no quantities, no routes and no schedules anywhere on this site, and support declines those questions; we publish no certificate we do not hold; and we publish no customer review that does not come from a verified order.
