MOTS-c (Mitochondrial Open Reading Frame of the 12S rRNA-c) is a mitochondrial-derived peptide of 16 amino acids that has garnered considerable attention in metabolic and cell biology research. Encoded within the mitochondrial genome, this short linear peptide is thought to participate in retrograde signaling\u2014communications from the mitochondrion to the nucleus\u2014and has been detected in multiple tissues and circulating biofluids in model organisms. Its primary sequence, Met\u2011Arg\u2011Trp\u2011Gln\u2011Glu\u2011Met\u2011Gly\u2011Tyr\u2011Ile\u2011Phe\u2011Pro\u2011Arg\u2011Lys\u2011Leu\u2011Arg, is highly conserved, making it a compelling candidate for cross\u2011species studies of mitochondrial function.<\/p>\n
In laboratory settings, synthetic MOTS-c is employed to probe fundamental pathways governing energy metabolism, including AMP\u2011activated protein kinase (AMPK) signaling and methionine cycle regulation. Researchers use the peptide in cell\u2011based and cell\u2011free models to examine shifts in mitochondrial respiration, glucose utilization, and fatty acid oxidation. Furthermore, its role is being mapped in longitudinal studies focusing on the molecular shifts observed during organismal aging and in the metabolic adaptations elicited by exercise. All investigations are conducted strictly in \u4f53\u5916<\/strong> and non\u2011clinical research contexts; MOTS\u2011c is not manufactured for, nor is it intended for, any application in humans or animals.<\/p>\n Bulk orders of MOTS\u2011c typically encompass quantities that far exceed the single\u2011vial sizes used in initial characterization experiments. Whereas a standard research purchase might involve 1\u202fmg, 5\u202fmg, or 10\u202fmg aliquots, a bulk order is generally understood to begin at the gram scale\u2014often 1 gram or more of lyophilized peptide. Such volumes are necessary when laboratories run large\u2011scale screening assays, perform extensive pharmacological profiling, or require a consistent lot for multi\u2011year comparative studies.<\/p>\n Suppliers that specialize in peptide synthesis routinely offer bulk quantities in a series of practical increments. Common bulk sizes for MOTS\u2011c include:<\/p>\n Opting for a bulk order provides economic advantages through significantly reduced cost per milligram. Manufacturing efficiency scales with batch size: once the solid\u2011phase synthesis, cleavage, and purification processes are established for a larger run, the marginal cost of additional peptide decreases. Bulk orders also allow the supplier to dedicate an entire synthesis column to a single project, minimizing cross\u2011contamination risk and ensuring batch uniformity. Lead times may be extended for very large quantities because of the need for more extensive lyophilization and quality\u2011control testing, but many suppliers prioritize bulk tickets to maintain smooth production flow.<\/p>\n For a relatively short synthetic peptide like MOTS\u2011c, the industry\u2011standard minimum order quantity for a bulk purchase is commonly 1 gram<\/strong>. This threshold is feasible because 16\u2011amino\u2011acid chains can be assembled with high efficiency using Fmoc solid\u2011phase peptide synthesis (SPPS) on a multi\u2011gram scale without encountering severe aggregation or deletion problems. Suppliers offering \u201coff\u2011the\u2011shelf\u201d MOTS\u2011c often list a 1\u2011gram SKU as their entry\u2011level bulk size.<\/p>\n When a research group requires non\u2011standard modifications, higher purity, or the peptide is being synthesized as a custom project (rather than taken from existing inventory), the MOQ may rise. Some manufacturers set a floor of 5 grams<\/strong> or even 10 grams<\/strong> for a de novo synthesis run. This is partly because the purification step\u2014typically reversed\u2011phase high\u2011performance liquid chromatography (RP\u2011HPLC)\u2014can result in significant yield loss, especially when a customer demands a purity exceeding 98%. To deliver the requested amount at the specified purity, the crude synthesis must start from a larger mass, and the supplier will not proceed unless the total batch size justifies the operational effort. The precise MOQ also hinges on the supplier\u2019s internal resin\u2011loading capacity and the footprint of their lyophilization equipment. Buyers evaluating suppliers should directly inquire whether the stated MOQ applies to catalog listings or to fully custom productions.<\/p>\n Several technical and logistical parameters determine the minimum order quantity a supplier will accept for bulk MOTS\u2011c:<\/p>\n A well\u2011prepared inquiry accelerates the quoting process and helps the supplier determine whether they can fulfill the order. Before contacting the manufacturer or distributor, a buyer should compile the following details:<\/p>\n Once the specifications are assembled, the buyer should reach out to the supplier\u2019s business development or sales team using a professional communication that includes the researcher\u2019s institutional affiliation, a brief description of the intended research (without revealing proprietary details), and the above\u2011mentioned parameters. The supplier will issue a formal quotation that outlines the price per gram, total amount, applicable packaging costs, estimated lead time, and the precise MOQ should it differ from the inquired amount. Buyers are advised to confirm that the quoted price includes a \u5206\u6790\u8bc1\u4e66<\/strong>, and to ask whether sample aliquots from the batch can be held for future analytical comparisons.<\/p>\n Suppliers differ in how they handle MOTS\u2011c bulk requests. Some maintain an inventory of catalog\u2011grade MOTS\u2011c in notable quantities\u2014for instance, 1\u2011gram, 5\u2011gram, or 10\u2011gram lots\u2014that can be dispatched within days to a few weeks. This stock model is practical for the unmodified wild\u2011type sequence that is in steady demand across academic and pharmaceutical research groups. Customers ordering from stock benefit from shorter turnaround and validated batch data, but may have limited flexibility regarding vial configuration or salt form.<\/p>\n Custom synthesis becomes the only route when the required peptide deviates from the standard sequence. Examples include isotopically labeled MOTS\u2011c for metabolomic tracing studies, fusion peptides, cyclic analogs, or variants containing non\u2011natural amino acids. Custom\u2011synthesis tickets invariably carry a higher minimum order quantity\u2014commonly 10 grams or more\u2014because the setup costs (resin preparation, amino acid derivatization, method development) must be amortized over a larger mass. Additionally, the lead time for custom projects is usually longer, as analytical methods must be validated specifically for the variant. Research groups needing only a few milligrams of a bespoke MOTS\u2011c analog may consider a small\u2011scale custom synthesis offer, often at a premium, but these are not considered bulk orders under the usual definition.<\/p>\n Purchasers of bulk MOTS\u2011c for research use should expect a comprehensive documentation package that supports both laboratory safety and regulatory compliance. The central document is the \u5206\u6790\u8bc1\u4e66\uff08CoA\uff09<\/strong>, which is batch\u2011specific and should contain:<\/p>\n A \u6750\u6599\u5b89\u5168\u6570\u636e\u8868\uff08MSDS\uff09<\/strong>, often termed Safety Data Sheet (SDS), is typically provided or available for download. It outlines proper handling (e.g., use in a fume hood, wear gloves and protective eyewear), storage recommendations (lyophilized powder at \u201320\u202f\u00b0C, protected from moisture and light), and emergency procedures. Many institutions also require this document as part of their chemical hygiene plan.<\/p>\n For international shipments, the buyer and supplier must jointly abide by the import\/export regulations of the originating and destination countries. While MOTS\u2011c is not listed on international controlled\u2011substance schedules in most jurisdictions, customs authorities occasionally scrutinize large quantities of synthetic peptides. To avoid clearance delays, the shipper\u2019s export documentation should clearly state: \u201cSynthetic peptide for \u4f53\u5916<\/em> research use only. Not for human or veterinary application.\u201d An invoice, packing list, and signed declaration of intended use are standard. Some countries additionally require an import permit or a letter from the receiving institution. Buyers should consult their institutional biosafety or compliance office well before the order is placed.<\/p>\n What is the typical MOQ for MOTS\u2011c?<\/strong> Can I order smaller quantities for preliminary studies?<\/strong> How is MOTS\u2011c shipped and stored?<\/strong> Does MOTS\u2011c come with a reliable purity guarantee?<\/strong> What information does the supplier need to begin a bulk synthesis?<\/strong> Research use only note: All products and information presented herein are strictly for laboratory research purposes.

Frequently Asked Questions About MOTS-c Bulk Orders<\/h2>\n
\nThe standard minimum order quantity for a bulk purchase is 1 gram. However, this figure can vary; some suppliers set a 5\u2011gram floor for custom synthesis runs, especially when modifications or extremely high purity are requested. Always verify the MOQ with the specific supplier you are contacting.<\/p>\n
\nYes. Most peptide suppliers offer MOTS\u2011c in milligram\u2011scale vials (e.g., 1\u202fmg, 5\u202fmg, 10\u202fmg) for feasibility experiments and dose\u2011response profiling. These smaller lots are not classified as bulk orders and therefore do not benefit from bulk pricing. When a project progresses and the need for a uniform large batch becomes clear, you can transition to a bulk order using the same supplier to maintain consistency.<\/p>\n
\nMOTS\u2011c is typically shipped as a lyophilized powder at ambient temperature. Because the dry peptide is chemically stable for short periods at room temperature, this mode of transport preserves its integrity. Upon receipt, the container should be transferred to a \u201320\u202f\u00b0C freezer for long\u2011term storage, away from humidity and light. After reconstitution in an appropriate solvent (e.g., sterile PBS, pH\u202f7.4, or DMSO for stock solutions), the peptide solution should be aliquoted and stored at \u201320\u202f\u00b0C or \u201380\u202f\u00b0C, with care taken to avoid repeated freeze\u2011thaw cycles.<\/p>\n
\nReputable manufacturers provide a CoA that specifies the batch\u2011specific purity measured by HPLC. For bulk orders, purities of \u226595% or \u226598% are standard, with \u226599% available upon request. The CoA also includes mass identity confirmation, so you can be confident in both the composition and the exact molecular weight of the material you receive.<\/p>\n
\nIn addition to the desired quantity and purity, they will ask for the full sequence, any terminal modifications, the required salt form, and the preferred packaging configuration. Providing a target delivery date and the destination country helps the supplier schedule the synthesis and prepare all necessary shipping documents.<\/p>\n
