\nBremelanotide is a synthetic cyclic heptapeptide with the amino acid sequence Ac-Nle-cyclo[Asp-His-D-Phe-Arg-Trp-Lys]-OH. In laboratory settings, it functions as a melanocortin receptor agonist, displaying binding affinity for multiple melanocortin receptor subtypes in in vitro<\/em> systems. This compound is supplied exclusively for research applications; it is not manufactured, packaged, or distributed for any purpose related to human or animal ingestion, administration, or treatment. Laboratories intending to buy Bremelanotide bulk wholesale<\/strong> are typically engaged in receptor pharmacology, neurobiological pathway analysis, or the development of novel chemical probes, all under strictly controlled experimental conditions.\n<\/p>\n \nThe molecule\u2019s structure features an acetylated norleucine residue at the N-terminus and a lactam bond between aspartic acid and lysine side chains, forming a cyclic core that stabilizes its bioactive conformation. Researchers rely on this well-characterized compound for binding assays, functional signaling studies, and structure-activity relationship investigations. Every shipment is labeled \u201cResearch Use Only,\u201d and purchasers must affirm that the material will be handled by qualified personnel in appropriate containment facilities.\n<\/p>\n \nThe empirical molecular formula of Bremelanotide is C50<\/sub>H68<\/sub>N14<\/sub>O9<\/sub>, corresponding to a molecular weight of 1024.17 g\/mol. The peptide is most commonly supplied as an acetate salt to enhance aqueous solubility, facilitating dissolution in typical assay buffers. For long-term stability, the lyophilized powder must be stored at -20 \u00b0C in a desiccated environment and protected from light. Repeated freeze-thaw cycles should be avoided; working aliquots can be prepared under an inert atmosphere where feasible.\n<\/p>\n \nEvery production batch is subjected to rigorous analytical characterization. High-performance liquid chromatography (HPLC) consistently demonstrates a purity level of \u226598%, with a detailed certificate of analysis (COA) issued for each lot. The COA documents the exact peptide content, counter-ion ratio, retention time, and mass confirmation via electrospray ionization mass spectrometry (ESI-MS) or matrix-assisted laser desorption\/ionization (MALDI-TOF). Laboratories that buy Bremelanotide bulk wholesale<\/strong> can also request a copy of the batch-specific proton nuclear magnetic resonance (1<\/sup>H-NMR) spectrum and amino acid analysis data. Where additional verification is desired, an aliquot can be sent to an independent third-party laboratory at the buyer\u2019s request.\n<\/p>\n \nThe acetate salt form delivers a net peptide content typically exceeding 80%, with the remainder being residual water and counter-ions. This composition is quantified by quantitative amino acid analysis and taken into account when preparing stock solutions. Because Bremelanotide contains tryptophan and histidine residues sensitive to oxidation, lyophilized vials are sealed under argon or nitrogen to safeguard integrity during transit and storage.\n<\/p>\n \nBremelanotide is widely employed as a reference agonist in melanocortin receptor research. Its affinity profile across the five known melanocortin receptors (MC1R through MC5R) makes it a versatile tool for distinguishing receptor subtype selectivity. In in vitro<\/em> radioligand binding assays, Bremelanotide competes with labeled \u03b1-melanocyte-stimulating hormone (\u03b1-MSH) analogs, allowing calculation of inhibition constants (Ki<\/sub>) at each recombinant receptor. Functional activity is routinely measured by quantifying cyclic adenosine monophosphate (cAMP) accumulation in HEK293 or CHO cells stably expressing the individual receptor subtypes.\n<\/p>\n \nA typical binding assay uses 125<\/sup>I-NDP-MSH ([Nle4<\/sup>,D-Phe7<\/sup>]-\u03b1-MSH) as the radioligand. Membranes prepared from transfected cell lines are incubated with Bremelanotide across a concentration range (e.g., 10-12<\/sup> to 10-5<\/sup> M), and specific binding is measured after equilibrium dialysis or filtration. Bremelanotide consistently exhibits high affinity for MC4R and MC1R, with comparatively lower affinity at MC3R and MC5R. These binding profiles underpin the rational design of next-generation ligands with altered selectivity, a common objective for groups that buy Bremelanotide bulk wholesale<\/strong> to sustain long-term medicinal chemistry projects.\n<\/p>\n \nCompetition curve analysis provides a full pharmacological profile: IC50<\/sub> values are converted to Ki<\/sub> using the Cheng-Prusoff equation, yielding reproducible numbers when assay conditions are strictly controlled. Because the cyclic heptapeptide structure is distinct from linear MSH peptides, researchers also assess dissociation kinetics and the influence of allosteric modulators on Bremelanotide binding.\n<\/p>\n \nDownstream signaling is frequently evaluated in cell lines expressing melanocortin receptors, where Bremelanotide stimulates Gs<\/sub> protein-coupled pathways leading to adenylyl cyclase activation. cAMP accumulation is measured by homogeneous time-resolved fluorescence (HTRF) or enzyme-linked immunosorbent assay (ELISA). Transfected HEK293 or CHO cells are treated with Bremelanotide for 30\u201360 minutes, after which intracellular cAMP levels are normalized to total protein content.\n<\/p>\n \nThese in vitro<\/em> setups support mechanistic studies into energy homeostasis and the neurobiological circuits associated with ingestive and reproductive behaviors. All protocols must be approved by the respective institutional ethical committees governing in vitro<\/em> and animal research, where applicable. Importantly, Bremelanotide is used in animal model systems solely under approved protocols that explore central nervous system pathways; the compound is never intended for diagnostic or therapeutic application in any species.\n<\/p>\n \nResearchers and institutions planning extended studies often buy Bremelanotide bulk wholesale<\/strong> to secure consistent batch quality and reduce per-unit cost. Quantities can be tailored from small research aliquots (milligram scale) to multi-gram or even kilogram lots for long-term combinatorial chemistry or screening programs. The ability to order peptide in bulk also facilitates custom enquiries for isotope-labeled versions (e.g., 13<\/sup>C- or 15<\/sup>N-labeled amino acid incorporation) or modified analogs featuring D-amino acid substitutions, pegylation, or fluorescent tags.\n<\/p>\n \nPricing is tiered according to the total amount ordered and the required purity threshold. Standard research-grade material (\u226598% purity) is the most common specification, but higher purity levels (\u226599%) can be achieved through additional preparative HPLC steps. Each quotation is transparent and details the cost per gram, anticipated synthesis time, and shipping fees.\n<\/p>\n \nEvery gram of Bremelanotide dispatched from a production facility is rigorously tested before release. The analytical panel includes reversed-phase HPLC for purity assessment, mass spectrometry for identity confirmation, and amino acid analysis to verify composition. For bulk wholesale orders, additional quality documentation is provided:\n<\/p>\n \nValidated protocols, including standard operating procedures for synthesis, cleavage, and purification, are followed without deviation. Any modification to the standard route is documented and shared with the buyer upon request.\n<\/p>\n \nShipping Bremelanotide internationally demands careful thermal management and adherence to cross-border regulations. Lyophilized peptide is transported in sealed glass vials placed inside insulated shipping containers with sufficient dry ice or ice packs to maintain -20 \u00b0C to -80 \u00b0C throughout transit. Temperature loggers can be included to record the cold chain and provide a digital readout upon receipt.\n<\/p>\n \nCustoms documentation is prepared to identify the contents accurately as \u201cresearch chemicals \u2013 not for human use.\u201d The commercial invoice and packing list state the CAS registry number (189691-06-3) and the applicable harmonized system code for peptide derivatives. These steps expedite clearance and reduce the risk of delays. Because Bremelanotide is not scheduled under any international drug convention, control status is generally limited to the standard oversight of research chemicals, though buyers must confirm the import requirements in their jurisdiction.\n<\/p>\n \nThe peptide is manufactured and sold exclusively for laboratory research use only<\/strong>. It is not intended for diagnostic, therapeutic, veterinary, or personal-care applications. Buyers undertake full responsibility for researching and complying with all local, state, and federal regulations that govern the import, storage, and use of research peptides. A material safety data sheet (MSDS) is included with every shipment, detailing physical properties, handling precautions, and first-aid measures.\n<\/p>\n \nAdditionally, the product is supplied in accordance with the European Union\u2019s Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH) regulation, when applicable, and analogous frameworks in other regions. Buyers should verify that their intended use falls within the explicit scope of research and does not stray into unlicensed activities. Any request implying human or animal use will be declined.\n<\/p>\n \nProcuring Bremelanotide in bulk begins with a clear specification of the desired quantity, purity level, and any necessary modifications (e.g., acetate salt or alternative counter-ion). Buyers can submit an inquiry through the supplier\u2019s website contact form or send a direct email message summarizing their requirements. A technical sales representative will respond to clarify details and provide a formal quotation within one business day.\n<\/p>\n \nThroughout the process, the customer can receive updates on synthesis progress and request an intermediate analytical report. The final shipment is released only after all quality specifications are met. Researchers who regularly buy Bremelanotide bulk wholesale<\/strong> can establish framework agreements to lock in pricing and secure dedicated synthetic slots for recurring orders.\n<\/p>\n \nResearch use only note:<\/strong> Bremelanotide is supplied solely for in vitro<\/em> laboratory research and experimental model systems under controlled protocols.
