Oxytocin is an endogenous nonapeptide belonging to the family of neurohypophyseal peptide hormones; chemically, it is a cyclic peptide with an intramolecular disulfide bridge. In scientific research, it is studied as a model compound for receptor pharmacology and peptide chemistry and as a reference standard in analytical work. This compound is offered as a freeze-dried powder of 10 mg per vial, exclusively for laboratory and research purposes.<\/p>\n
Oxytocin is a peptide of nine amino acids with the sequence Cys-Tyr-Ile-Gln-Asn-Cys-Pro-Leu-Gly-NH2<\/sub>The cysteine \u200b\u200bresidues at positions 1 and 6 form a disulfide bridge, causing the molecule to carry a closed ring of six amino acids with a tail of three residues and an amidated C-terminus. This combination of a fixed ring and a flexible tail makes the compound a widely used model in the study of peptide receptor recognition.<\/p>\n In research models, oxytocin binds to the oxytocin receptor (OXTR), a rhodopsin-like class A receptor with seven transmembrane domains. In vitro, this receptor primarily couples to G proteins of the Gq\/11<\/sub>-type, after which phospholipase C forms the membrane lipid PIP2<\/sub> It splits into inositol triphosphate and diacylglycerol; the former initiates the release of intracellular calcium in cell models, while the latter activates protein kinase C. Because Oxytocin differs from the related nonapeptides of the same hormone family at only two positions, it also exhibits weaker cross-reactivity with related receptor subtypes in cell culture systems. Consequently, Oxytocin is used as a model compound and reference substance in scientific research.<\/p>\n In a laboratory context, Oxytocin occurs in the following research areas, among others:<\/p>\n Fiecare dintre aceste aplica\u021bii implic\u0103 cercetare controlat\u0103 de laborator sau pe modele preclinice.<\/p>\n Oxytocin falls under the category of freeze-dried investigational peptides in vial form within our range. Researchers in this category regularly combine the compound with other peptides that are studied via their own biochemical target. While Oxytocin targets a class A G-protein-coupled receptor, other components within the same product line have been specifically chosen to cover enzymatic or other receptor-mediated targets. These compounds share the freeze-dried vial form but differ fundamentally in amino acid composition and investigated mechanism.<\/p>\n Oxytocin is supplied as a freeze-dried powder in a sealed glass vial containing a standardized quantity of 10 mg. Unlike a solid tablet form, this is a lyophilized material: for analytical or cell biological work, the material is dissolved in a suitable solvent. The powder is hygroscopic and absorbs moisture upon exposure to ambient air, which affects the accuracy of gravimetric work.<\/p>\n Store the closed vial in a cool, dry place, protected from direct light, in the original packaging; the disulfide bridge is the most sensitive structure in the molecule, so oxidative and thermal stress must be kept to a minimum. Handle the compound with standard laboratory precautions: work in a clean environment, use appropriate protective equipment, and prevent cross-contamination. Keep the packaging out of reach of unauthorized persons.<\/p>\n A controlled purity of \u2265 99% (HPLC) is maintained for this lyophilisate. The vial contains the peptide as freeze-dried material, without active secondary ingredients.<\/p>\nDomenii de cercetare<\/h2>\n
