The mitochondrial open reading frame of the twelve S ribosomal RNA type-c, commonly referred to as MOTS-c, represents a significant advancement in the study of metabolic regulation and cellular homeostasis. This product, identified by CAS number 1627580-64-6 and model designation V40974, is a synthetic analog of the naturally occurring 16-amino acid peptide derived from the mitochondrial genome. Unlike many signaling molecules encoded by the nuclear genome, MOTS-c originates within the mitochondria, acting as a potent retrograde signaling messenger that communicates the metabolic status of the organelle to the broader cellular environment. This specific preparation offers a high-performance biochemical tool characterized by a verified purity threshold of 98% or higher, ensuring minimal batch-to-batch variation for applications requiring consistent molecular specificity. The peptide is supplied as a white to off-white lyophilized solid powder, a physical presentation deliberately selected to preserve the structural integrity and bioactivity of the peptide during extended storage and transport. This off-white to white appearance is indicative of high-quality synthesis and proper lyophilization cycles, which remove residual moisture without compromising the peptide backbone or side-chain functionalities. The product is synthesized using solid-phase peptide synthesis (SPPS) methodologies followed by rigorous high-performance liquid chromatography (HPLC) purification to achieve the stated 98% purity level. The peptide sequence corresponds exactly to the endogenous human MOTS-c variant, ensuring that downstream biochemical interactions accurately reflect physiological mechanisms without species-specific discrepancies. Upon reconstitution in appropriate aqueous buffers or sterile solutions, the powder rapidly dissolves to yield a clear to slightly hazy solution, depending on the ionic strength of the diluent, with optimal solubility observed in slightly acidic to neutral pH buffers. For reconstitution, it is recommended to use sterile deionized water or a compatible physiological buffer system. The molecular weight of this peptide, calculated from its amino acid composition, is approximately 2174.5 Daltons, and researchers are advised to confirm this via mass spectrometry upon receipt as part of standard quality assurance protocols. As a regulator of nuclear gene expression, MOTS-c has been demonstrated in controlled laboratory environments to influence metabolic pathways sensitive to AMPK activation, thereby modulating glucose uptake, fatty acid oxidation, and mitochondrial biogenesis. In cellular models, this peptide has shown the capacity to counteract age-dependent insulin resistance and to promote cellular resilience under conditions of energetic stress. The lyophilized powder format of model V40974 offers significant practical advantages, including excellent thermal stability when stored desiccated at minus twenty degrees Celsius. Under these recommended storage conditions, the product remains stable for twelve to eighteen months without detectable degradation, as verified by accelerated stability studies using HPLC and mass spectrometry. Each batch of this product undergoes comprehensive quality control testing, including peptide content determination, net peptide weight analysis, and bacterial endotoxin screening to ensure compliance with standard biochemical purity requirements. The white to off-white solid powder does not contain any added carriers, preservatives, or bulking agents such as mannitol or trehalose unless explicitly requested, providing a pure peptide matrix that is free from potentially interfering excipients. For routine handling, it is recommended to centrifuge the vial briefly before opening to ensure that any loose powder collects at the bottom of the container, minimizing electrostatic loss of the fine solid material. Following reconstitution in a suitable solvent such as sterile deionized water or an appropriate buffer system, the peptide solution should be aliquoted into single-use volumes to avoid repeated freeze-thaw cycles, which may accelerate aggregation or deamidation. The structural authenticity of this MOTS-c preparation is routinely verified by amino acid analysis (AAA) and matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) mass spectrometry, providing unequivocal confirmation of the correct molecular identity for CAS 1627580-64-6. Furthermore, reverse-phase HPLC chromatograms generated for each production batch demonstrate a main peak purity exceeding the nominal 98% threshold, with related substance profiles indicating the absence of significant deletion or truncation sequences. This product is intended for trained professionals in biochemical laboratories who require highly characterized peptides for controlled in vitro or ex vivo experimental systems. The white to off-white appearance of the lyophilized cake or powder is a visual indicator of successful lyophilization, and any deviation from this color specification would prompt an immediate quality investigation. Because MOTS-c functions as a hormone-like peptide that can circulate and affect distant tissues in vivo, this synthetic preparation provides a defined alternative to less pure extracts or recombinant expression systems that may introduce host cell protein contaminants. The small molecular size of this 16-mer peptide allows for rapid diffusion in tissue culture media and efficient penetration of extracellular spaces, enabling investigators to achieve consistent molar concentrations with minimal precipitation issues. When used in combination with cell culture models of metabolic stress, the 98% pure product demonstrates reproducible dose-response characteristics, with effective concentrations typically ranging from low nanomolar to low micromolar depending on the specific cell type and endpoint measured. Storage of the unopened lyophilized white to off-white solid powder at controlled room temperature for short intervals during active use is acceptable, but long-term preservation requires the stability provided by freezer storage. For quality control purposes, each unit of model V40974 is labeled with the product name, CAS number 1627580-64-6, net peptide weight, purity percentage, and lot-specific expiration date, facilitating traceability and inventory management in regulated laboratory environments. The peptide is supplied in amber glass vials with a fluoropolymer-coated stopper to minimize adventitious adsorption and leaching of plasticizers that could interfere with sensitive biological assays. Finally, this product is distributed as a high-purity biochemical reagent, and each batch is accompanied by a certificate of analysis detailing the specific purity, net peptide content, solubility profile, and storage recommendations to support systematic and reproducible scientific investigation.
