Importance of Lot-Specific Verification for CJC-1295 (No DAC)
In modern biochemical research, peptide purity directly dictates experimental reproducibility. CJC-1295 without Drug Affinity Complex (No DAC)—also known as Modified GRF 1-29—is a 29-amino-acid synthetic peptide designed as a GHRH analog. Studied as a long-acting growth-hormone-releasing hormone that sustains GH and downstream IGF-1 levels for tissue repair research, even minor synthesis impurities or trifluoroacetic acid (TFA) salt variations can skew in vitro cell culture signaling assays or animal model neuroendocrine observations.
Lot-specific verification via a third-party Certificate of Analysis guarantees that the exact sample in your laboratory matches its declared sequence, molecular weight, and purity score. By reviewing third-party testing documentation prior to reconstituting reagents, primary investigators eliminate variables related to structural truncation, improper racemization, or microbiological contamination. To review documentation across our full inventory of research compounds, researchers can browse our catalog of all peptides or directly access our central COA lookup database.
Locating the Lot Number on Your CJC-1295 (No DAC) Vial Label
Every research-grade vial produced for PX1 Research undergoes strict inventory tracking and batch serialization. To locate your CJC-1295 (no dac) coa lot number, examine the primary vial label attached to your glass container. The lot number is printed cleanly along the lower edge of the secondary panel, designated clearly with the prefix 'LOT:' followed by an alphanumeric string (e.g., LOT: CJC-ND-2024-08A).
It is critical to distinguish between the catalog stock number (SKU) and the lot production number. While the SKU identifies the specific product formulation—such as CJC-1295 (No DAC)—the lot number isolates the exact synthesis batch, purification run, and lyophilization cycle. Ensure that both the lot number on the outer container packaging and the direct vial label correspond prior to entering the code into the verification portal.
Navigating the PX1 Research COA Search Interface
Accessing analytical records through PX1 Research is designed to be seamless for institutional procurement officers and laboratory technicians. Navigate directly to the dedicated COA documentation center, where our searchable repository hosts high-resolution, unedited analytical documentation for every lot released from our facilities.
To perform a lookup, input the exact alphanumeric sequence found on your vial label into the primary search bar. The system will instantaneously query our ISO 17025 accredited laboratory database, generating a downloadable PDF containing the complete analytical dossier. If your laboratory manages high-volume baseline inventories or requires bulk batch certificates for grant reporting, contact our institutional support team via the wholesale portal for automated lot certificate archiving.
Interpreting High-Performance Liquid Chromatography (HPLC) Purity Reports
High-Performance Liquid Chromatography (HPLC) serves as the industry gold standard for quantifying chemical purity in synthetic peptides. The HPLC chromatogram included in your CJC-1295 (No DAC) COA maps the retention time of the main peptide peak against potential synthesis side-products, including truncated sequences, deletion peptides, and baseline column noise.
When evaluating the HPLC chromatogram, the area under the curve (AUC) of the primary peak determines overall purity. PX1 Research enforces a baseline threshold of ≥98.0% purity for all CJC-1295 (No DAC) batches. Minor secondary peaks represent acceptable trace degradation products or counter-ions. A clean, single sharp peak with minimal tailing confirms that the compound is suitable for sensitive receptor-binding and tissue repair research assays without interference from sequence variants.
Evaluating Mass Spectrometry (MS) Identity & Molecular Mass Data
While HPLC confirms peptide purity, Mass Spectrometry (MS) verifies structural identity by measuring the exact mass-to-charge ratio (m/z) of the molecule. The theoretical molecular weight of CJC-1295 (No DAC) (C152H252N44O42) is calculated at approximately 3367.9 Da. The MS spectrum on your lot certificate must reflect a clear observed mass matching this theoretical target within standard spectrometer tolerances (±1 Da).
Electrospray Ionization Mass Spectrometry (ESI-MS) reports typically show multiple charge states, such as [M+3H]3+ or [M+4H]4+ signals. The calculated monoisotopic or average mass derived from these charge peaks confirms that the 29-amino-acid chain has been synthesized in correct sequence without amino acid substitutions or missing residues. Accessing comprehensive MS metrics ensures researchers are deploying authentic GHRH analogs in downstream analytical procedures.

Endotoxin Verification and Bioburden Standards in Lyophilized Peptides
Endotoxins—lipopolysaccharides (LPS) derived from the cell walls of Gram-negative bacteria—pose a significant threat to cell line viability and in vivo rodent physiological studies. Even pure peptides can harbor trace pyrogens if post-synthesis purification and lyophilization environment parameters are not rigorously controlled.
PX1 Research subjects every batch of CJC-1295 (No DAC) to Limulus Amebocyte Lysate (LAL) or recombinant Factor C endotoxin testing. The resulting COA documents the precise bioburden level, expressed in Endotoxin Units per milligram (EU/mg). Our standard operating procedures dictate an endotoxin threshold of <0.1 EU/mg, far surpassing general industry norms. Low endotoxin values ensure that observed cellular responses in tissue repair protocols stem solely from GHRH receptor signaling rather than background inflammatory activation.
Physical Characterization, Solubilization, and Reconstitution Parameters
The COA documentation also details physical appearance standards prior to laboratory manipulation. High-purity CJC-1295 (No DAC) appears as a uniform, white to off-white lyophilized cake or powder. Any visual discoloration, clumping, or foreign particulate matter indicates batch compromise and warrants immediate quarantine.
Reconstitution protocols require precise fluid dynamics to preserve peptide backbone stability. Reagents should be solubilized using sterile Bacteriostatic Water or laboratory-grade diluents depending on your specific protocol requirements. Researchers calculating solvent volume ratios for precise micromolar concentrations should utilize our standardized reconstitution calculator to eliminate manual concentration errors before executing laboratory assays.
Comparative Analytical Profiles: CJC-1295 (No DAC) vs. Related GHRH Analogs
When designing comparative secretagogue protocols, researchers frequently evaluate multiple growth hormone secretagogues and GHRH analogs alongside CJC-1295 (No DAC). Understanding the structural differences among these research compounds is critical when comparing COA data and expected half-life profiles.
For example, CJC-1295 with DAC incorporates a Maleimidopropionic acid linker that covalently binds to circulating albumin, significantly extending its plasma half-life in animal models compared to the rapid clearance of CJC-1295 (No DAC). Similarly, shorter-chain GHRH analogs like Sermorelin represent the truncated GRF 1-29 sequence without the specific stabilizing amino acid substitutions found in CJC-1295 (No DAC) (such as D-Ala2, Gln8, Ala15, and Leu27). Furthermore, researchers studying synergistic GH release frequently pair GHRH analogs with growth hormone secretagogue receptor (GHSR) agonists such as Ipamorelin. Comparing lot documentation across these distinct classes ensures uniform purity baselines across multi-arm experimental designs.
Storage, Stability, and Handling Protocols for Reconstituted Solutions
Lyophilized CJC-1295 (No DAC) exhibits superior long-term stability when stored at -20°C in a desiccated environment, shielded from light exposure. Upon receipt, laboratory personnel should verify that the packaging seals are intact and cross-reference the batch number with our online repository before cold-chain transfer.
Once reconstituted in an aqueous buffer, the peptide becomes significantly more susceptible to enzymatic degradation, oxidation, and aggregation. Reconstituted solutions should be aliquoted into single-use microcentrifuge tubes to prevent repeated freeze-thaw cycles and maintained at 2°C to 8°C for short-term experimentation (under 14 days) or frozen at -80°C for extended periods. Detailed guidelines on handling peptide stability parameters are routinely published in our GHRH research series.
