MOTS-C 30mg — Vial Spec, Reconstitution Math & COA

30mg MOTS-c Vial Overview and Laboratory Format Selection

A 30mg vial of MOTS-c (Mitochondrial Open Reading Frame of the 12S rRNA Type-C) provides a high-yield mass of pure lyophilized peptide designed for multi-assay experimental series, high-throughput in vitro screens, or longitudinal preclinical animal models. Investigators selecting a 30mg unit typically operate laboratories requiring consistent stock solutions across extended experimental timelines without the lot-to-lot variance that can introduce confounding variables into metabolic or exercise-capacity research.

While standard single-assay formats frequently utilize lower mass fills such as 5mg or 10mg, high-concentration working stock preparation relies on larger formats to streamline volumetric workflows. At PX1 Research, laboratory supply formats are maintained under stringent quality management protocols; researchers evaluating bulk requirement options can review our complete catalog of research peptides or inspect specific single-vial offerings on the dedicated MOTS-c research product page. If a specific 30mg fill size is temporarily out of stock or custom-synthesized on demand, equivalent total mass can be achieved by aggregating standardized 5mg or 10mg lyophilized units.

Molecular Profile and Preclinical Mechanism of Action

MOTS-c is a 16-amino-acid peptide encoded within the mitochondrial genome, specifically originating from the 12S ribosomal RNA region. Unlike nuclear-encoded peptides, mitochondrial-derived peptides (MDPs) act as retrograde signaling molecules that communicate cellular energy status directly to the nucleus under condition of metabolic stress.

Preclinical studies suggest that MOTS-c acts primarily through activation of the AMP-activated protein kinase (AMPK) pathway. In cell culture models and rodent experiments, MOTS-c administration has been observed to modulate folate-dependent one-carbon metabolism, enhance glucose utilization, and promote systemic metabolic homeostasis. Furthermore, in animal models evaluated for physical performance parameters, MOTS-c demonstrated the capacity to enhance skeletal muscle insulin sensitivity and modulate exercise-capacity responses, making it a critical focus of study in metabolic regulation research.

Reconstitution Mathematics for 30mg Lyophilized Vials

Accurate reconstitution is paramount to ensuring reproducible concentration metrics in laboratory assays. Reconstituting a 30mg lyophilized cake of MOTS-c requires precise volumetric measurement of bacteriostatic water (0.9% benzyl alcohol) or sterile laboratory-grade water for injection, depending on the downstream assay requirements.

To achieve target working concentrations, researchers can utilize the following standard reconstitution ratios for a 30mg vial mass: • 1.0 mL Diluent Volume: Yields a final concentration of 30.0 mg/mL (30 µg/µL). • 2.0 mL Diluent Volume: Yields a final concentration of 15.0 mg/mL (15 µg/µL). • 3.0 mL Diluent Volume: Yields a final concentration of 10.0 mg/mL (10 µg/µL). • 5.0 mL Diluent Volume: Yields a final concentration of 6.0 mg/mL (6 µg/µL).

For non-standard volumes or specific micromolar concentration targets across complex microplate layouts, scientists are encouraged to verify volumetric dilutions using our interactive reconstitution calculator. When adding diluent, introduce the solvent slowly along the inner glass wall of the vial, allowing gentle passive dissolution without vigorous agitation to prevent peptide shear stress or air bubble entrapment.

Aliquot Planning and Storage Stability Protocols

Lyophilized MOTS-c retains optimal chemical stability when stored at -20°C to -80°C in a desiccated environment, shielded from light exposure. Once reconstituted into liquid solution, peptides undergo accelerated degradation pathways including hydrolysis and deamidation if maintained at room temperature or subject to repeated freeze-thaw cycles.

To maximize liquid stability, single-use aliquoting should be performed immediately following initial dissolution. Reconstituted stock should be divided into micro-centrifuge tubes using polypropylene low-binding plastics, sealed, and frozen immediately at -80°C. Working aliquots stored at 2°C to 8°C should generally be utilized within 7 to 14 days, whereas frozen aliquots stored at -80°C maintain structural integrity for extended periods provided freeze-thaw events are strictly avoided.

Quality Assurance: HPLC, MS, and Endotoxin Verification

Every production lot of MOTS-c distributed by PX1 Research undergoes rigorous third-party analytical testing to guarantee laboratory-grade purity and batch consistency. Quality control standards require high-performance liquid chromatography (HPLC) to confirm peptide purity exceeds 98.0%, alongside mass spectrometry (MS) to verify precise molecular weight (1875.1 Da expected theoretical mass).

Because mitochondrial peptides are frequently utilized in sensitive cell culture lines and in vivo rodent models, endotoxin contamination can confound biological markers by triggering non-specific inflammatory responses. PX1 Research enforces strict bacterial endotoxin testing (LAL assay), certifying levels remain below established research safety thresholds (<0.01 EU/mg). Investigators can review or download the verified lot-specific Certificate of Analysis corresponding to their exact vial serial number directly through our analytical compliance portal.

Comparative Analysis: MOTS-c vs. Humanin and SS-31

Within the domain of mitochondrial signaling and metabolic research, MOTS-c is evaluated alongside other key targeted peptides such as Humanin research compounds and SS-31 (Elamipretide). While all three compounds target organelle-level pathways, their primary molecular mechanics diverge significantly.

MOTS-c functions predominantly as a nuclear retrograde signaling factor that alters metabolic gene expression via the AICAR/AMPK axis, regulating systemic carbohydrate and lipid dynamics. In contrast, Humanin acts primarily as a cytoprotective mitochondrial peptide that inhibits Bax-mediated apoptosis and attenuates oxidative stress in neuronal and cardiovascular models. SS-31 operates through a distinct physical mechanism, binding selectively to cardiolipin within the inner mitochondrial membrane to restore cristae structure and optimize electron transport chain efficiency. Selecting between these compounds depends on whether the investigator's target endpoint is gene-regulated metabolic adaptation, anti-apoptotic signaling, or structural membrane restoration.

Vial Format Selection: 30mg High-Yield vs. Standard Mass Fills

Selecting the appropriate vial size requires balancing experimental scale, reagent stability, and financial efficiency. High-yield 30mg vials represent an optimal choice for institutional laboratories running high-throughput screening assays, continuous animal administration protocols, or collaborative study groups requiring centralized stock preparation.

Conversely, smaller format sizes (such as 5mg or 10mg fills) are preferable for small-scale pilot studies, initial dose-response curve establishing assays, or protocols where liquid storage capacity is severely restricted. Utilizing smaller vials minimizes the risk of stock loss due to accidental thaw events or localized contamination. For high-volume research initiatives, institutional purchasing teams can access scaled logistics through our bulk laboratory supply program.

Preclinical Applications in Exercise and Metabolic Assays

In vitro and animal model data indicate that MOTS-c plays a direct role in regulating skeletal muscle metabolism during physical stress. In rodent treadmill models, exogenous MOTS-c administration has been documented to increase exercise capacity, attenuate high-fat diet-induced insulin resistance, and alter heat shock protein responses.

Cellular assays employing primary myocytes or C2C12 cell lines demonstrate that MOTS-c treatment stimulates glucose uptake independently of classical insulin signaling cascades. These findings position MOTS-c as a primary benchmark compound for studying metabolic flexibility, sarcopenia prevention mechanisms, and mitochondrial adaptational pathways in response to simulated exercise stressors. Additional literature and data sheets are accessible via the PX1 research database.

Handling Protocols and Solvent Compatibility Parameters

Proper handling of 30mg MOTS-c vials requires adherence to aseptic laboratory procedures. Prior to reconstitution, the sealed vial should be allowed to equilibrate to ambient room temperature to prevent condensation from forming inside the vessel upon cap removal.

MOTS-c exhibits excellent solubility in sterile aqueous buffers including phosphate-buffered saline (PBS, pH 7.4) and standard bacteriostatic water. However, for long-term liquid stock preparation intended for sub-zero storage, reconstitution in sterile water prior to final dilution into buffered culture media is recommended to avoid salting-out effects or premature peptide aggregation.
