\nMOTS-c (Mitochondrial Open Reading Frame of the 12S rRNA-c) is a 16\u2011amino\u2011acid peptide encoded within the mitochondrial genome, specifically from the 12S rRNA region. Unlike the vast majority of cellular peptides that originate from nuclear genes, MOTS-c is translated within mitochondria and can then be released into the cytosol and circulation. This unusual biogenesis positions MOTS-c as a unique signaling molecule that links mitochondrial gene expression to systemic metabolic regulation.\n<\/p>\n
\nResearch over the past decade has demonstrated that MOTS-c plays a significant role in metabolic homeostasis and cellular energy balance. In cell\u2011based and animal model experiments, the peptide has been observed to influence glucose utilization, promote AMP\u2011activated protein kinase (AMPK) signaling, and enhance mitochondrial respiration. These observations support a model in which MOTS-c acts as a retrograde mitochondrial signal, translating information about the mitochondrial metabolic state into broader cellular adjustments. Consequently, MOTS-c raw material for sale is increasingly sought by academic laboratories and pharmaceutical research teams investigating mitochondrial biology, metabolic disorders, and mechanisms of cellular stress adaptation.\n<\/p>\n
\nThe capacity of MOTS-c to modulate pathways linked to mitochondrial biogenesis and energy expenditure has made it a subject of intense study in contexts such as cellular aging, exercise physiology, and insulin signaling. In vitro experiments with cultured myotubes and hepatocytes have shown enhanced glucose uptake and improved mitochondrial function following exposure to synthetic MOTS-c, while in vivo rodent studies have documented altered metabolic profiles and endurance performance. Because MOTS-c is naturally present in human plasma and its levels fluctuate with physiological conditions, researchers are actively exploring its potential as a biomarker for mitochondrial function. For all these experimental directions, access to highly purified, well\u2011characterized MOTS-c raw material for sale is a critical prerequisite, and the peptide must meet rigorous quality standards to ensure reproducible data.\n<\/p>\n
\nThe synthetic MOTS-c supplied for laboratory research is a highly purified lyophilized powder that meets defined analytical criteria. Every batch is synthesized using solid\u2011phase peptide synthesis (SPPS) and purified by reverse\u2011phase high\u2011performance liquid chromatography (RP\u2011HPLC). The final product is supplied as a sterile, non\u2011pyrogenic, lyophilized powder sealed under inert gas in glass vials that protect the material from moisture and oxidation. The amino acid sequence is Methionine\u2011Arginine\u2011Tryptophan\u2011Glutamine\u2011Glutamic acid\u2011Methionine\u2011Glycine\u2011Tyrosine\u2011Isoleucine\u2011Phenylalanine\u2011Arginine\u2011Glycine\u2011Lysine\u2011Proline, which corresponds to the mature MOTS-c form and carries a monoisotopic molecular weight of approximately 2,174.5 g\/mol.\n<\/p>\n
\nThe standard purity specification for MOTS-c raw material for sale is \u226595% as determined by analytical RP\u2011HPLC at 214 nm. Identity is confirmed by electrospray ionization mass spectrometry (ESI\u2011MS) or matrix\u2011assisted laser desorption\/ionization time\u2011of\u2011flight mass spectrometry (MALDI\u2011TOF MS). In addition to routine HPLC and MS, amino acid analysis following acid hydrolysis verifies the expected molar ratios of the component residues, and peptide\u2011content determination by UV spectrophotometry at 280 nm (based on the absorbance of the single tryptophan and tyrosine residues) allows accurate quantification of the peptide amount in each vial, correcting for counterions and residual water. Endotoxin levels are controlled to below 1 EU\/mg, making the product suitable for cell\u2011based assays where LPS contamination could confound readouts of metabolic or inflammatory pathways.\n<\/p>\n
\nResearchers can procure MOTS-c raw material for sale in a range of predispensed quantities, typically 1 mg, 5 mg, and 10 mg vials, with custom bulk packaging available for high\u2011throughput studies or institutional core facilities. The lyophilized form is recommended for long\u2011term storage; it should be reconstituted shortly before use in an appropriate sterile buffer (e.g., phosphate\u2011buffered saline, 10 mM Tris\u2011HCl, or water for injection) according to the experimental solubility requirements. Following reconstitution, the solution can be aliquoted and stored at \u201320\u00b0C or \u201380\u00b0C to minimize freeze\u2011thaw degradation. The manufacturer seals each vial under a dry argon or nitrogen atmosphere and includes detailed resuspension guidelines with the shipment.\n<\/p>\n
\nAll lots of MOTS-c raw material for sale are manufactured in monitoring environments consistent with ISO\u2011certified quality management systems. Each synthesis and purification step is documented, and the final material undergoes a comprehensive panel of release tests. A Certificate of Analysis (CoA) accompanies every order and serves as a verifiable summary of the batch\u2011specific attributes. Stability studies conducted under recommended storage conditions (\u201320\u00b0C, protected from light and moisture) indicate that the lyophilized peptide retains its purity and biological activity for at least 24 months. Real\u2011time and accelerated stability testing continues to refine the assigned shelf life and to validate the packaging integrity.\n<\/p>\n
\nPurity is assessed by reverse\u2011phase HPLC using a C18 column and a linear gradient of acetonitrile in water with 0.1% trifluoroacetic acid. The main peak typically accounts for more than 95% of the integrated area. Mass identity is confirmed by MALDI\u2011TOF MS or ESI\u2011MS, with the observed molecular ion matching the theoretical monoisotopic mass within 1 Da. For additional confirmation, peptide mapping after tryptic digestion and tandem mass spectrometry (LC\u2011MS\/MS) can be performed on representative batches. Quantification of the peptide content per vial is determined by UV absorbance at 280 nm using a calibrated extinction coefficient, ensuring that the stated quantity accurately reflects the net peptide amount rather than the total lyophilized weight, which includes counterions and water.\n<\/p>\n
\nThe CoA for each batch of MOTS-c raw material for sale includes the batch\u2011specific lot number, date of manufacture, retest date, and critical quality attributes: purity percentage, mass\u2011spectral identity, net peptide content, endotoxin level, and appearance of the lyophilized cake. Residual solvent analysis (typically for trifluoroacetic acid and acetonitrile) and elemental impurity profiling may be included, depending on the testing panel selected. These documents can be downloaded from the supplier\u2019s customer portal upon request, allowing procurement and quality\u2011assurance teams to review the data before initiating experiments. Clients with additional validation requirements can discuss bespoke testing packages during the quotation process.\n<\/p>\n
\nThe primary use of MOTS-c raw material for sale is in preclinical research aimed at deciphering mitochondrial\u2011to\u2011nuclear communication and metabolic control. In cellular models, synthetic MOTS-c is added to culture medium to examine its effects on insulin\u2011independent glucose uptake, AMPK phosphorylation, and expression of genes involved in oxidative metabolism. Experiments in differentiated C2C12 myotubes, L6 myocytes, and primary hepatocytes have provided evidence that MOTS-c enhances glucose transporter type 4 (GLUT4) translocation and increases oxygen consumption rate, consistent with a shift toward oxidative energy production. These findings underscore the peptide\u2019s value as a molecular tool in studies of type 2 diabetes, obesity, and metabolic syndrome \u2013 all pursued at the basic\u2011science level without any therapeutic inference.\n<\/p>\n
\nAnother active area of investigation focuses on mitochondrial biogenesis and cellular aging. Research groups have reported that exogenous MOTS-c can stimulate mitochondrial DNA replication and expression of PGC\u20111\u03b1, a master regulator of mitochondrial genesis, in aged or metabolically compromised cells. Such effects are examined in the context of sarcopenia, age\u2011related decline in muscle function, and the cellular senescence that accompanies mitochondrial dysfunction. Because synthetic MOTS-c is chemically defined and scalable, it offers a reproducible probe for dissecting the signaling cascades that follow mitochondrial\u2011peptide release, including potential crosstalk with the nuclear factor erythroid 2\u2011related factor 2 (Nrf2) antioxidant response pathway.\n<\/p>\n
\nThe peptide is also utilized in exercise physiology research. Rodent studies have shown that MOTS-c administration, combined with exercise, can modify metabolic adaptation and endurance capacity, pointing to an endogenous role in the organism\u2019s response to physical activity. Translational laboratories use MOTS-c raw material for sale to explore how mitochondrial\u2011derived peptides may coordinate muscle\u2011liver\u2011adipose tissue communication during exercise and fasting. Because these investigations are strictly limited to laboratory models, any extrapolation to human performance is premature, but the availability of high\u2011purity peptide enables well\u2011controlled, reproducible experiments.\n<\/p>\n
\nA reliable supply chain for MOTS-c raw material for sale is essential for long\u2011term research programs. The supplier accepts purchase orders from accredited academic institutions, pharmaceutical R&D departments, and authorized distributors. Standard catalog sizes are typically held in inventory and can be dispatched within a few business days. Larger or custom\u2011formatted orders are processed with a lead time of approximately 2\u20133 weeks, allowing sufficient time for synthesis, purification, and the full quality\u2011control cycle. Temperature\u2011controlled packaging using validated dry\u2011ice shipments ensures the peptide remains at \u201320\u00b0C or below during transit, regardless of the destination\u2019s ambient conditions.\n<\/p>\n
\nFor investigators planning large\u2011scale screening campaigns or longitudinal animal studies, bulk quantities of MOTS-c raw material for sale are available. The minimum order for bulk pricing is typically 100 mg, with scaled discounts applied to 250 mg, 500 mg, and 1 g quantities. Customers requiring an analog, a labeled derivative (e.g., with stable isotopes for mass\u2011spectrometry quantification), or a modified sequence can request custom peptide synthesis services. Quote requests are handled through a dedicated account manager and are usually returned within 24 hours, along with a detailed technical proposal and timeline.\n<\/p>\n
\nAll MOTS-c shipments are packed with dry ice in insulated containers designed to maintain cryogenic conditions for up to 72 hours. Upon receipt, the lyophilized peptide should be immediately transferred to a \u201320\u00b0C or \u201380\u00b0C freezer, protected from light and humidity. Before opening the vial, it is advisable to allow the container to equilibrate to room temperature inside a desiccator to prevent condensation on the product. Once reconstituted, peptide solutions should be aliquoted into single\u2011use volumes and stored frozen. Repeated freeze\u2011thaw cycles compromise peptide integrity and may lead to aggregation or loss of activity; therefore, any unused reconstituted material should be discarded after one thaw. Storage recommendations are based on real\u2011time stability data that support product integrity under these conditions.\n<\/p>\n
