- Registry Cross-Reference: PubChem CID 56841945 corresponds to the 29-residue unconjugated sequence and to the formula C152H252N44O42 given above. Registry records for this compound family apply the CJC-1295 name across both this form and the DAC-conjugated form, so confirm the batch against its Certificate of Analysis rather than the trade name alone.
- Variant Distinction: This entry describes the unconjugated 29-residue form, which terminates at Arg29 and carries no maleimide group. The DAC-conjugated analog is a separate catalog entry with a higher molecular mass; the two are not interchangeable in an assay.
Analytical & COA Specifications
- Analytical Purity (RP-HPLC)
- ≥ 98.5% area normalization under UV detection at λ = 214 nm and 220 nm.
- Identity Confirmation (RP-HPLC RT + UV vs. reference)
- Main peak retention time and UV spectrum conform to the reference standard.
- Physical Characterization
- Dense, white to off-white lyophilized solid cake/powder.
Handling & Stability
Storage. Store dry solid desiccated at -20°C to -80°C, protected from atmospheric moisture and direct light.
Solubility. Soluble in sterile laboratory-grade deionized water (≥ 10 mg/mL), sterile Phosphate-Buffered Saline (PBS, pH 7.4, ≥ 5 mg/mL), or dilute 0.1% sterile acetic acid for stock stabilization in in vitro assay applications.
- Solution Stability & Degradation Parameters: Lacks the C-terminal Drug Affinity Complex (DAC) bioconjugation moiety, resulting in shorter aqueous half-life profiles compared to DAC-conjugated analogs; aliquot into single-use laboratory fractions at -20°C to eliminate degradation from repeated freeze-thaw cycles.
Mechanism & Literature
Structural Engineering Focus: Synthetic 29-amino acid peptide derived from the active amino-terminal core of growth hormone-releasing hormone (GHRH1--29). Engineered with four strategic amino acid substitutions—D-Ala2, Gln8, Ala15, and Leu27—specifically designed to resist rapid enzymatic cleavage by dipeptidyl peptidase-4 (DPP-4) and oxidative degradation without including the covalent albumin-binding DAC linker.
Cellular Pathways Investigated: Evaluated in primary pituitary cell cultures and receptor-transfected cell lines (e.g., HEK293 expressing human GHRHR) to measure selective binding affinity (Ki) for the Growth Hormone-Releasing Hormone Receptor (GHRHR), stimulation of adenylyl cyclase, intracellular cyclic AMP (cAMP) accumulation, and downstream transcriptional activation of growth hormone (GH) expression.

Technical Laboratory FAQs
How does CJC-1295 (No DAC) differ from standard Sermorelin [GRF(1-29)]?
While Sermorelin matches native GHRH1--29, CJC-1295 (No DAC) incorporates four structural modifications (D-Ala2, Gln8, Ala15, Leu27), enhancing enzymatic resistance to DPP-4 cleavage in laboratory assay media.
What is the functional difference between CJC-1295 with DAC and without DAC?
CJC-1295 (No DAC) lacks the maleimidopropionic acid bioconjugation group, preventing covalent albumin coupling; this produces rapid receptor binding and clearance kinetics in in vitro cellular models rather than prolonged bioconjugation.
What vehicle is recommended for preparing in vitro CJC-1295 (No DAC) working stocks?
Sterile deionized water or sterile PBS (pH 7.4) provides rapid dissolution. For long-term stock stability in cell culture media preparation, a dilute 0.1% sterile acetic acid solution helps prevent deamidation of glutamine residues.
