Purchase MOTS-c Peptide

Where to Purchase MOTS-c Peptide for Laboratory Research

To purchase MOTS-c peptide for laboratory research, investigators must select suppliers that offer verified identity, sequence confirmation, and lot-specific documentation. MOTS-c (Mitochondrial Open Reading Frame of the 12S rRNA-c) is a 16-amino-acid peptide encoded within the mitochondrial genome. Preclinical investigators studying cellular bioenergetics, metabolic signaling, and mitochondrial dysfunction require reference-grade material to ensure reproducible assay results across experimental runs.

PX1 Research supplies high-purity MOTS-c peptide synthesized under strict quality controls in USA-based facilities. Every batch undergoes third-party verification using reversed-phase high-performance liquid chromatography (RP-HPLC) and mass spectrometry (MS) to guarantee chemical purity exceeding 99%. Laboratories can review complete batch documentation via our centralized research hub prior to procuring reference standards for experimental models.

Vendor Selection Criteria: Sourcing High-Purity MOTS-c

When evaluating options to purchase MOTS-c, biomedical research teams must establish clear quality benchmarks. Peptides utilized in delicate cell culture systems or animal models require strict monitoring for residual reagents, TFA salts, heavy metals, and bacterial endotoxins. Inconsistent batch purity can introduce confounding variables that compromise metabolic assays and gene expression analyses.

A reliable supplier must provide documented evidence of manufacturing quality for every lot. Key evaluation criteria include:

1. Third-Party Certificate of Analysis (COA): Lot-specific COAs detailing raw integration values from HPLC and mass-to-charge ratios from MS assays. 2. Ultra-Low Endotoxin Levels: Quantitative chromogenic LAL testing ensuring endotoxin concentrations remain under 0.01 EU/mg to protect cellular assays from inflammatory signaling artifacts. 3. USA-Based Manufacturing and Distribution: Domestic synthesis within ISO 17025 accredited or GMP-compliant facilities, mitigating supply chain delays and degradation from prolonged transit. 4. Full Lot Traceability: Complete tracking from solid-phase peptide synthesis (SPPS) through lyophilization, storage, and fulfillment.

PX1 Research fulfills all four parameters, offering expedited same-day dispatch from facility hubs in California and Arizona. Investigators can access our complete line of research peptides with guaranteed lot consistency.

Mitochondrial Derived Peptides: MOTS-c Structure and Signaling Pathways

MOTS-c belongs to a novel class of signal transducers known as mitochondrial-derived peptides (MDPs). Unlike nuclear-encoded peptides, MOTS-c originates from a short open reading frame within the mitochondrial 12S ribosomal RNA gene. Preclinical literature demonstrates that upon induction of cellular stress, MOTS-c translocates from the mitochondrion to the nucleus, where it acts as a genomic transcription factor regulating metabolic homeostasis.

In cell culture models, MOTS-c signaling directly interacts with the folate cycle and 5'-adenosine monophosphate-activated protein kinase (AMPK) pathways. By inhibiting the folate cycle, MOTS-c increases 5-aminoimidazole-4-carboxamide ribonucleotide (AICAR) levels, leading to downstream activation of AMPK. This unique nuclear-mitochondrial communication axis makes the compound a central subject of study within metabolic research peptides and bioenergetic signaling frameworks.

Researchers evaluating mitochondrial peptides frequently study MOTS-c alongside related MDPs to map overlapping metabolic cascades. For instance, investigators often compare MOTS-c mechanisms with Humanin, another key MDP involved in cytoprotection, as well as cardiolipin-targeted mitochondrial peptides like SS-31. Comparing these molecules helps clarify how mitochondrial signaling coordinates systemic metabolic responses.

Preclinical Applications: Mitochondrial Function and Exercise-Capacity Research

Preclinical investigations into MOTS-c focus primarily on its capacity to modulate systemic bioenergetics, glucose clearance, and physical workload capacity in model organisms. Rodent models subjected to high-fat diets demonstrate that MOTS-c administration can attenuate diet-induced insulin resistance and weight gain by enhancing fatty acid oxidation in skeletal muscle tissue.

Furthermore, animal studies demonstrate that MOTS-c treatment significantly increases exercise capacity, running distance, and skeletal muscle adaptation in both young and aged mice. The peptide appears to upregulate heat shock response elements and nuclear factor erythroid 2-related factor 2 (Nrf2) pathways, boosting endogenous antioxidant defenses during physiological stress. These findings have positioned MOTS-c as a primary standard in preclinical research on exercise mimetics, sarcopenia mitigation, and metabolic longevity.

Laboratories investigating metabolic regulation can review detailed preclinical literature and analytical protocols in our MOTS-c scientific guide to optimize experimental design.

Reconstitution and Laboratory Storage Protocols for MOTS-c

Maintaining chemical stability is critical when handling lyophilized peptides. MOTS-c is supplied as a sterile, lyophilized white powder that must be stored under controlled thermal conditions to prevent hydrolytic degradation or oxidation of sensitive amino acid residues.

Upon arrival at the research facility, un-reconstituted MOTS-c vials should be stored at -20°C or -80°C for long-term stability. Prior to opening, vials must be allowed to equilibrate to room temperature inside a desiccator cabinet to minimize moisture condensation on the cake.

For reconstitution in aseptic laboratory settings, bacteriostatic water (0.9% benzyl alcohol) or sterile endotoxin-free water is recommended depending on the requirements of the biological assay. The solvent should be directed against the inner glass wall of the vial rather than sprayed directly onto the peptide cake. Gentle swirl mixing—avoiding vigorous vortexing—ensures complete dissolution without inducing peptide aggregation. Detailed procedures are available in our guide on peptide storage and reconstitution.

Analytical Quality Control: HPLC, Mass Spectrometry, and Endotoxin Standards

High-performance liquid chromatography (RP-HPLC) is the standard method for determining the chemical purity of synthetic peptides. Chromatographic separation identifies and quantifies synthesis impurities, truncated sequences, or oxidation products. PX1 Research mandates that every batch of MOTS-c display a clear single-peak profile indicating high purity.

Mass spectrometry (ESI-MS or MALDI-TOF) is subsequently utilized to confirm exact molecular mass and sequence fidelity, verifying that the synthesized peptide matches the theoretical mass of 2174.6 Da. Additionally, because bacterial lipopolysaccharides (LPS) can stimulate inflammatory cascades in cell cultures and animal models, strict endotoxin limits are enforced. Every lot distributed by PX1 Research undergoes quantitative LAL assay testing, confirming compliance with rigorous analytical standards.

Institutional Sourcing and Bulk Procurement for Research Facilities

Academic institutions, contract research organizations (CROs), and corporate biotechnology facilities requiring large volumes of reference peptides can utilize customized supply workflows. Large-scale animal studies and high-throughput screening assays demand lot consistency across extended timelines to eliminate batch-to-batch variability.

PX1 Research supports volume requirements through dedicated laboratory accounts. Institutional buyers looking to secure continuous supply lines can submit requests through our wholesale program to access reserved lot allocations, custom vial sizing, and bulk pricing schedules tailored for institutional budgets.
