Overview of CJC-1295 DAC in Research
CJC-1295 DAC is a synthetic peptide analog designed for controlled laboratory investigations. It is a derivative of growth hormone–releasing hormone (GHRH) that has been modified with a Drug Affinity Complex (DAC). This structural modification creates a covalent bond between the peptide and circulating albumin in research models, substantially extending the observational half‑life of the molecule. In vitro and in vivo study systems benefit from this prolonged presence, enabling researchers to design experiments with less frequent administration than would be required for un‑modified GHRH analogs.
The peptide is produced through solid‑phase synthesis and purified to high standards suitable for research-grade applications. It is routinely supplied as a sterile, lyophilized powder that is free of additives unless requested. Each batch is analyzed for peptide content, identity, and purity using orthogonal analytical techniques such as high‑performance liquid chromatography (HPLC) and mass spectrometry (MS). The expected molecular weight of CJC-1295 DAC is approximately 3647.2 Da, confirming the presence of the DAC moiety. Because the lyophilized form is hygroscopic, proper handling during reconstitution with an appropriate solvent such as sterile water or a bacteriostatic solution helps maintain its integrity for downstream experimental use.
Researchers frequently incorporate CJC-1295 DAC into studies exploring protein‑binding kinetics, receptor signaling cascades, and pharmacodynamic modeling. Its DAC‑mediated albumin binding is a useful tool for examining how sustained ligand exposure influences downstream targets in a controlled environment. The peptide is not intended for therapeutic use of any kind and must only be utilized in a laboratory setting compliant with institutional safety guidelines.
Determining Minimum Order Quantity (MOQ) for Bulk Orders
When planning a CJC-1295 DAC bulk order, the minimum order quantity (MOQ) is a key parameter set by the supplier. MOQs for research peptides vary widely depending on the manufacturer’s production capacity, the scale of the synthesis, and the intended use case. For CJC-1295 DAC, the MOQ can range from as low as 10 mg for small‑volume research packs up to 100 g or more for large‑scale distribution orders. However, the term “bulk” in the peptide supply chain typically refers to net peptide quantities starting at 1 gram, with many suppliers defining their bulk MOQ at 5 grams, 10 grams, or even 25 grams for high‑purity material.
Several factors influence the specific MOQ applied to a CJC-1295 DAC purchase:
- Purity specification: Higher purity requirements (e.g., ≥99% HPLC purity) may necessitate a larger MOQ because of the additional purification steps and yield losses.
- Peptide form: Lyophilized powder is standard; if a custom formulation or aliquoting into smaller vials is requested, the minimum may be expressed as a total amount per shipment or as a minimum order value.
- Synthesis scale: Full‑scale GMP‑like or research‑grade reactors are optimized for gram‑scale batches; small milligrams are often prepared as a “resynthesis,” which can carry a higher unit cost and a different MOQ.
- Supplier policy: Some exporters set a flat MOQ of 1 g for any bulk peptide, while others allow flexible quantities provided the total invoice meets a predetermined threshold.
It is not uncommon for a supplier to quote a CJC-1295 DAC bulk MOQ of 10 grams of net peptide when analytical documentation packages, such as full Certificate of Analysis and stability data, are included. Researchers and distributors are strongly advised to discuss the MOQ directly with the technical sales team before placing an order. Clarifying whether the MOQ refers to the weight of the pure peptide or the total filled weight (including any excipients) prevents misunderstandings. In addition, verifying whether the MOQ can be split into multiple smaller packs—for example, ten 1‑gram vials versus one 10‑gram container—can align the order with laboratory storage and handling workflows.
Packaging and Storage Conditions for Bulk CJC-1295 DAC
Shipping and Primary Packaging
Bulk CJC-1295 DAC is shipped as a dry, lyophilized powder in sealed, chemically inert containers. Standard containers include glass vials with fluoropolymer‑lined caps, multiple‑vial packs, or single large‑capacity borosilicate jars for gram‑scale quantities. To safeguard peptide stability during transit, the powder is packaged under vacuum or an inert gas atmosphere such as argon or nitrogen, and desiccant sachets are included to absorb moisture. Ambient temperature shipping is typical for lyophilized peptides because the dry form is structurally robust under short‑term temperature fluctuations; however, the use of insulated shipping boxes or cold packs may be offered for sensitive destinations or extremely high‑value cargo.
Receiving institutions should inspect all packaging upon arrival. Any damage to seals, vials, or the external secondary container must be documented and reported to the supplier immediately.
Long‑Term Storage Recommendations
For long‑term storage, every effort should be made to maintain the peptide at −20°C or lower, protected from light and moisture. Consistent low temperature slows chemical degradation pathways such as deamidation, oxidation, and aggregation, preserving the peptide’s analytical profile for months to years. Short‑term working aliquots can be kept at 2–8°C if they will be consumed within a few days, but repeated freeze‑thaw cycles should be avoided. A common practice in research laboratories is to reconstitute a small portion of the bulk powder, aliquot it into single‑use volumes, and store those aliquots at −80°C, while the un‑reconstituted bulk container remains securely sealed at −20°C.
Bulk packaging configurations offer flexibility. For a 5‑gram order, a supplier might package the peptide as fifty 100‑mg vials, ten 500‑mg vials, or a single container holding the full quantity. Each approach has implications for sterility maintenance and ease of use. Choosing multi‑vial packaging can be beneficial when the peptide needs to be distributed across different experimental arms without exposing the entire stock to ambient conditions.
Quality Assurance and Documentation for Bulk Orders
Reputable peptide exporters provide a comprehensive set of batch‑specific documents alongside every bulk shipment. The cornerstone of this documentation is the Certificate of Analysis (COA), which reports the analytical results for the exact batch shipped. A standard COA for CJC-1295 DAC includes:
- Purity by HPLC: Usually expressed as area‑%, with acceptance criteria commonly set at ≥98% or ≥99% for advanced research applications.
- Molecular weight confirmation by mass spectrometry: Electrospray (ESI‑MS) or matrix‑assisted laser desorption/ionization (MALDI‑TOF) spectra are compared against the theoretical mass of approximately 3647.2 Da. A mass accuracy within ±1 Da is typical.
- Peptide content: Determined by amino acid analysis or nitrogen content analysis to quantify the net peptide fraction in the lyophilized material.
- Appearance and solubility: Description of the white to off‑white powder and brief solubility data in recommended solvents.
- Endotoxin levels (upon request): For cell‑based studies, endotoxin testing (LAL assay) can be performed, with limits often set below 1 EU/mg.
Beyond the COA, bulk orders are accompanied by a Safety Data Sheet (SDS) that outlines handling procedures, personal protective equipment (PPE) recommendations, and emergency measures. For institutional procurement, batch‑specific identifiers—including lot number, manufacturing date, retest or re‑analysis date, and storage conditions—provide full traceability. This traceability supports research reproducibility and aligns with laboratory quality management practices. Many suppliers operate under internationally recognized quality guidelines, such as those derived from ISO 9001 principles, and may offer documentation packages suitable for regulatory submissions in a research context. Researchers are encouraged to request examples of quality documents before committing to a bulk order to ensure the analytical depth meets their experimental requirements.
Process for Placing a Bulk Order of CJC-1295 DAC
Placing a bulk order for CJC-1295 DAC is a multi‑step process that requires clear communication between the buyer and the supplier. The following workflow can help ensure a smooth transaction and delivery of research‑grade material:
1. Specify Your Research Requirements
Begin by preparing a detailed inquiry that includes:
- Desired net peptide quantity (e.g., 10 g, 50 g, 100 g).
- Minimum purity acceptance (e.g., >98% by HPLC).
- Packaging preferences (single bulk container or subdivided into smaller vials).
- Any additional testing needs, such as endotoxin analysis, residual solvent profile, or heavy metal testing.
2. Confirm the MOQ, Lead Time, and Pricing
The supplier will respond with a formal quotation that states the CJC-1295 DAC bulk order minimum quantity applicable to your specifications, the price per gram at that scale, and the expected production or dispatch lead time. Custom synthesis runs for larger quantities may require 4–8 weeks, whereas stock material might ship within days. Verify whether the price includes shipping, insurance, and any applicable duties. For research institutions or distributors, payment is typically arranged via wire transfer, with proforma invoice issuance before production begins.
3. Provide Institutional or Distributor Documentation
Buyers must supply their organization’s official details, including a valid tax registration or institutional identifier. Many exporters require a completed end‑use statement, certifying that CJC-1295 DAC will be used exclusively for laboratory research and not for human or veterinary application. This declaration is a critical compliance document that may also be needed for customs clearance.
4. Coordinate Shipping and Regulatory Compliance
Discuss the shipping method and temperature control with the supplier’s logistics team. Most bulk peptide shipments are sent via express courier services, with tracking and thermologgers if cold‑chain transport is requested. Importantly, both the exporting and importing countries may have specific regulations for research peptides. Buyers should investigate whether CJC-1295 DAC requires an import permit or a license under their jurisdiction. Customs brokers often ask for a packing list, commercial invoice, and the COA/SDS. Providing these in advance can minimize clearance delays. Distributors reselling the peptide must additionally ensure that their onward supply chain does not violate any local or international trade restrictions applicable to research‑only chemicals.
5. Inspect and Store Upon Receipt
Once the shipment arrives, immediately compare the received quantity and packaging against the order and the packing list. Inspect the containers for any signs of damage. Transfer the lyophilized peptide to the recommended storage conditions (−20°C protected from light and moisture) as outlined in the accompanying documentation. Record the lot numbers in the laboratory inventory system and file the COA for future reference.
