When looking to buy Oxytocin Acetate 2mg for laboratory research, selecting a supplier offering verified identity, purity, and batch-to-batch consistency is critical for experimental accuracy. PX1 Research provides high-purity, USA-manufactured Oxytocin Acetate 2mg lyophilized powder, accompanied by lot-specific third-party HPLC and mass spectrometry analysis for rigorous in vitro and preclinical experimental protocols.
To buy Oxytocin Acetate 2mg with complete confidence, laboratory researchers require fully transparent quality documentation. Impurities or residual reagents in synthetic peptides can alter receptor-binding kinetics, artifactually alter cell culture assays, or invalidate baseline data in animal models. PX1 Research addresses these challenges by subjecting every production lot to independent laboratory analysis before release. Institutional investigators can explore our complete portfolio of high-purity nonapeptides and signaling molecules via our catalog of research peptides.
Oxytocin Acetate is a synthetic nonapeptide featuring a distinct cyclic structure formed by a disulfide bridge between two cysteine residues at positions 1 and 6. Its primary amino acid sequence is Cys-Tyr-Ile-Gln-Asn-Cys-Pro-Leu-Gly-NH2 (with a intramolecular Cys1-Cys6 disulfide bond). The acetate salt form enhances stability and solubility in aqueous buffers commonly utilized in laboratory research environments.
The molecular weight of free oxytocin is approximately 1007.19 g/mol. The rigid cyclic hexapeptide ring combined with a flexible tripeptide C-terminal tail governs its precise binding affinity for the oxytocin receptor (OXTR). Molecular studies documented in our peptide research hub detail how slight alterations to this cyclic framework can dramatically shift receptor selectivity between oxytocin and related neurohypophyseal hormone receptors.
Oxytocin functions primarily as a high-affinity peptide agonist at the oxytocin receptor (OXTR), a class A rhodopsin-like G-protein coupled receptor (GPCR). Upon ligand binding, OXTR couples predominantly to the Gq/11 class of heterotrimeric G-proteins. Preclinical in vitro assays demonstrate that this coupling activates phospholipase C-beta (PLC-β), initiating the hydrolysis of phosphatidylinositol 4,5-bisphosphate (PIP2) into inositol 1,4,5-trisphosphate (IP3) and diacylglycerol (DAG).
The generation of IP3 triggers the rapid release of intracellular calcium ions (Ca2+) from the endoplasmic reticulum into the cytosol. Elevated cytosolic calcium binds to calmodulin, activating plasma membrane and intracellular enzymes such as myosin light-chain kinase (MLCK) in smooth muscle models. Additionally, OXTR activation stimulates downstream signaling cascades including the protein kinase C (PKC) pathway and the mitogen-activated protein kinase (MAPK/ERK) pathway, which modulate gene expression, cellular proliferation, and long-term receptor desensitization mechanisms.
In published scientific literature, Oxytocin Acetate is widely evaluated across diverse experimental models. Researchers utilize this compound to probe neuroendocrine regulation, central nervous system signaling networks, and peripheral smooth muscle physiology. In vitro data indicate that oxytocin receptor activation regulates localized cellular contraction, intercellular junction integrity, and inflammatory mediator expression in tissue cultures.
In preclinical animal models, researchers investigate oxytocin pathways to understand the neurobiological underpinnings of social-behavior pathways, bonding dynamics, anxiety-like responses, and stress mitigation. Rodent studies frequently examine how central administration of oxytocin modulates amygdala circuitry and hypothalamic-pituitary-adrenal (HPA) axis reactivity. Furthermore, smooth-muscle cell assays utilize Oxytocin Acetate to benchmark calcium flux kinetics, receptor dimerization, and selective agonist/antagonist interactions.
Oxytocin belongs to a evolutionary conserved family of cyclic nonapeptides that includes arginine vasopressin and synthetic structural analogues. Because these peptides share significant sequence homology—differing by only two amino acids at positions 3 and 8—comparative receptor-binding studies are essential for mapping signal transduction specificity and receptor crosstalk.
In structural comparative studies, researchers frequently benchmark Oxytocin Acetate against related candidates such as Arginine Vasopressin, which acts primarily on V1a, V1b, and V2 receptors, and long-acting synthetic agonists like Carbetocin. While vasopressin exhibits higher affinity for vasopressinergic receptors governing osmoregulation and vascular tone, oxytocin displays preferential selectivity for OXTR. Evaluating these compounds side-by-side in competitive binding assays allows investigators to delineate GPCR selectivity profiles and cross-reactivity thresholds.
Proper handling and reconstitution of Oxytocin Acetate 2mg are critical to preserving peptide secondary structure and preventing premature degradation. High-purity lyophilized cakes should be equilibrated to room temperature inside a desiccator prior to opening to minimize atmospheric moisture condensation.
For most cell culture and receptor-binding assays, reconstitution in sterile, deaerated bacteriostatic water or standard phosphate-buffered saline (PBS, pH 7.4) is recommended. To reconstitute, gently inject the sterile solvent down the inner glass wall of the vial. Allow the liquid to absorb into the lyophilized matrix, then gently swirl the vial until completely dissolved. Avoid vigorous vortexing or shaking, as shearing forces and surface aeration can induce aggregation or denaturation of cyclic peptide bonds.
Oxytocin Acetate 2mg is supplied as a desiccated, sterile lyophilized powder to maintain chemical stability during transport and storage. In its dry form, the peptide exhibits robust stability when stored at -20°C or -80°C in a manual defrost freezer away from light exposure.
Once reconstituted into aqueous solution, the peptide's shelf life decreases significantly. Reconstituted stock solutions should be divided into single-use experimental aliquots using low-binding polypropylene microcentrifuge tubes and stored at -80°C. Repeated freeze-thaw cycles must be strictly avoided, as thermal fluctuations promote hydrolysis of the peptide backbone and oxidation of the disulfide bridge.
PX1 Research enforces strict quality control standards for every lot of Oxytocin Acetate 2mg. Chemical purity is verified via Reverse-Phase High-Performance Liquid Chromatography (RP-HPLC), ensuring a purity threshold of ≥98%. Mass Spectrometry (ESI-MS) is simultaneously performed to confirm exact molecular weight and structural identity, verifying the absence of truncated sequences or incomplete synthesis side-products.
In addition to purity and identity confirmation, PX1 Research evaluates total endotoxin content using quantitative Limulus Amebocyte Lysate (LAL) assays. Maintaining sub-threshold endotoxin levels (<0.01 EU/μg) is vital for preclinical research, as bacterial endotoxins can activate Toll-like receptors (TLR4) in cell cultures and animal models, producing false-positive inflammatory artifacts that compromise experimental integrity.
For academic departments, contract research organizations (CROs), and institutional laboratories requiring larger material volumes, PX1 Research provides streamlined procurement workflows. Qualified institutions can access scaled pricing and bulk supply through our dedicated wholesale research account portal.
