Oxytocin acetate is the acetate salt of oxytocin, the cyclic nine-residue neuropeptide that signals through the oxytocin receptor. Amino Club supplies it as a lyophilised research powder for in-vitro laboratory work.
About Oxytocin Acetate
The sequence is Cys-Tyr-Ile-Gln-Asn-Cys-Pro-Leu-Gly-NH2, closed into a six-residue ring by a disulfide bridge between the two cysteines, with a three-residue tail. It differs from vasopressin at only two positions, which is why selectivity between the oxytocin receptor and the vasopressin V1a receptor is a recurring question in binding studies rather than a given.
The oxytocin receptor is a class-A G-protein-coupled receptor signalling principally through Gq/11, phospholipase C and intracellular calcium release, with reported Gi coupling in some systems. Supplying the peptide as an acetate salt rather than a trifluoroacetate one matters for cell-based work, because residual trifluoroacetate from purification can itself affect cultured cells and confound low-concentration assays.
What the research covers
In-vitro literature on oxytocin spans two fairly separate fields. In smooth-muscle physiology it is the classical contractile agonist in isolated uterine and mammary tissue preparations, and the bioassay against which receptor antagonists are characterised. In neuroscience it is studied as a central neuromodulator: receptor distribution and binding, effects on neuronal firing in slice preparations, and interaction with dopaminergic and serotonergic systems in animal models of social behaviour. Receptor-selectivity work against the vasopressin receptors runs through both.

Handling Oxytocin Acetate
Supplied lyophilised in a sealed vial. Oxytocin is one of the less stable small peptides in solution: the disulfide bridge is susceptible to reduction and exchange, and aqueous solutions lose potency measurably over days even when refrigerated. Laboratories generally store the dry powder below −18 °C, prepare solutions in small single-use volumes, keep them cold and dark, and avoid repeated freeze-thaw cycles. Allow the vial to reach room temperature before opening so that moisture does not condense onto the powder.

Certificates, delivery and terms
This batch ships with the Certificate of Analysis carrying the batch number printed on its label; how that is tested and released is set out on the lab testing page. Delivery, customs and returns are covered on the shipping page, common questions on the FAQ, and quantity pricing through bulk and wholesale. Supplied for in-vitro laboratory research only: not a medicine, not a supplement, not for human or veterinary use, and no dosing or administration guidance is provided — see the research use policy.
