General description:	Oxytocin is a nonapeptide hormone produced in the hypothalamus and secreted by the posterior pituitary. It stimulates uterine contractions and lactation. The USP reference standard enables bioassay validation, potency testing, and structural identity confirmation in oxytocin products. The USP biologics peptides category encompasses a diverse range of therapeutic peptides that are essential in managing various medical conditions. These peptides, typically consisting of amino acid sequences of 40 residues or less, are critical for the development of high-quality medicines. The USP provides comprehensive standards, reference materials, and analytical procedures to ensure the identity, quality, purity, and consistency of peptide therapeutics throughout their lifecycle. The United States Pharmacopeia (USP) provides quality standards for biologics to ensure their safety, efficacy, and quality throughout the manufacturing process. These standards assist manufacturers in adhering to regulatory requirements and help safeguard public health by reducing risks associated with biologics.
Other Notes:	Sales restrictions may apply.
