CJC-1295 DAC (CAS 863288-34-0) is a modified 30-amino acid tetrasubstituted peptide derivative of Growth Hormone-Releasing Hormone (GHRH 1-29). The compound is engineered with a bioconjugated Drug Affinity Complex (DAC) moiety, specifically an N-epsilon-3-(maleimidopropionyl)lysine modification at the C-terminus. This covalent attachment enables selective binding to circulating serum albumin following administration in animal models, effectively shielding the peptide from enzymatic cleavage by dipeptidyl peptidase IV (DPP-IV).
When procurement teams search to source analytical-grade CJC-1295 DAC online, understanding this structural modification is paramount. In native GHRH and short-acting analogs, rapid cleavage between Ala2 and Asp3 limits the biological plasma half-life to mere minutes. By contrast, the albumin-bound CJC-1295 complex demonstrates extended stability in preclinical rodent models, extending the half-life to several days and enabling sustained activation of the GHRH receptor (GHRH-R) on pituitary somatotropes.
In vitro and in vivo studies indicate that CJC-1295 DAC acts as a selective agonist at the GHRH receptor. Upon binding to the GHRH-R, the peptide activates the G-protein-coupled receptor cascade, initiating adenylate cyclase activity and elevating intracellular cyclic adenosine monophosphate (cAMP). This signaling pathway stimulates both the transcription and exocytosis of growth hormone (GH) from anterior pituitary cells.
Preclinical evaluations in rodent models demonstrate that sustained GHRH-R activation via CJC-1295 DAC leads to a dose-dependent increase in basal plasma GH concentration without disrupting the physiological pulsatile secretion pattern. Downstream, elevated GH levels stimulate hepatic synthesis and secretion of Insulin-like Growth Factor 1 (IGF-1). Researchers utilize this compound within the peptide research repository to evaluate endocrine axis signaling, nitrogen retention, collagen synthesis, and cellular repair mechanisms in mammalian tissue models.
When designing comparative secretagogue protocols, investigators often evaluate CJC-1295 DAC against non-conjugated GHRH analogs and ghrelin receptor (GHS-R1a) agonists. The inclusion of the maleimide linker fundamental to the DAC modification alters both pharmacokinetics and physiological signaling dynamics compared to unmodified peptides.
While CJC-1295 without DAC exhibits a rapid clearance profile requiring multiple daily administrations in animal models, CJC-1295 DAC maintains steady-state plasma concentration over extended observation periods. Furthermore, combining GHRH analogs with selective ghrelin mimetics such as Ipamorelin target research compound or traditional secretagogues like GHRP-6 research peptide is frequently studied in vitro to examine synergistic pituitary stimulation. Combining distinct receptor target mechanisms allows researchers to probe dual-pathway activation without causing desensitization.
Procuring high-purity peptides online requires strict validation standards to avoid baseline variance in experimental models. Lower-tier suppliers often provide unverified material contaminated with trifluoroacetic acid (TFA) salts, truncated synthesis fragments, or high bacterial endotoxin levels. High endotoxin content can induce non-specific inflammatory responses in cellular assays, compromising data integrity.
PX1 Research establishes the industry standard for research-grade synthesis. Every lot of CJC-1295 DAC undergoes stringent analytical verification at an independent ISO 17025 accredited laboratory. Researchers reviewing analytical data receive complete lot-specific Certificates of Analysis (COA) containing double-wave Reverse-Phase High-Performance Liquid Chromatography (RP-HPLC) chromatograms and Liquid Chromatography-Mass Spectrometry (LC-MS) spectra ensuring purities exceeding 98.0%. For laboratories requiring large-volume acquisition, our platform supports established institutional workflows via bulk research account options.
Ensuring structural integrity across synthesized peptides demands multi-tiered analytical chemistry protocols. Simple spectrophotometric methods are insufficient for identifying target sequence variations or racemization products. PX1 Research implements three mandatory testing vectors for every synthesized lot:
1. Reverse-Phase HPLC: Quantifies chemical purity by measuring total peak area, confirming target compound purity at or above 98.0% while detecting trace synthesis impurities. 2. Electrospray Ionization Mass Spectrometry (ESI-MS): Verifies exact molecular mass (C152H252N44O42, theoretical MW: ~3647.2 Da), confirming correct amino acid sequence assembly and full maleimidopropionyl incorporation. 3. Bacterial Endotoxin Testing: Utilizes Chromogenic Limulus Amebocyte Lysate (LAL) assays to confirm endotoxin levels strictly below <0.5 EU/mg, preventing cell culture toxicity or non-specific innate immune activation.
CJC-1295 DAC is supplied as a sterile, lyophilized cake inside glass vials sealed under inert atmosphere. To preserve molecular integrity, unopened vials must be stored at -20°C or -80°C in a desiccated environment. Lyophilized peptides remain stable at frozen temperatures for up to 24 months from the date of synthesis.
Reconstitution should be conducted under strict aseptic conditions within a laminar flow hood. Laboratory standard reconstitutions typically employ sterile Bacteriostatic Water (0.9% benzyl alcohol) or sterile 0.9% Sodium Chloride injection solution. The solvent should be directed down the internal glass wall of the vial rather than sprayed directly onto the lyophilized pellet to avoid physical shear stress on the peptide backbone. Swirl gentle circular motions until complete dissolution is achieved; avoid violent agitation or vortexing. Reconstituted solutions should be stored at 2°C to 8°C and utilized within target protocol timeframes.
In preclinical research settings, sustained growth hormone elevation induced by CJC-1295 DAC has been investigated across multiple physiological systems. Animal models of muscle atrophy, cartilage breakdown, and delayed wound healing demonstrate marked responses to sustained GHRH-R activation.
Data derived from rodent assays show enhanced myofibrillar protein synthesis, accelerated connective tissue repair, and elevated extracellular matrix expression following administration of continuous GHRH agonists. Furthermore, investigations into metabolic signaling indicate that sustained IGF-1 secretion influences lipolysis in adipose tissue and supports cellular nutrient partitioning. Researchers exploring these pathways can reference our growth hormone secretagogues section for expanded comparative literature.
