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 (≥ 15 mg/mL), sterile Phosphate-Buffered Saline (PBS, pH 7.4, ≥ 10 mg/mL), or dilute sterile 0.1% acetic acid for stock stabilization in in vitro assay applications.
- Handling & Solution Kinetics: Both components lack covalent bioconjugation linkers (non-DAC), exhibiting standard peptide half-life profiles in aqueous buffers; prepare working solutions freshly, avoid high-shear vortexing, and store single-use aliquots at -20°C to eliminate degradation from repeated freeze-thaw cycles.
Mechanism & Literature
Dual-Pathway Synergy Model: Investigated in preclinical neuroendocrine and pituitary cell culture models to examine non-competitive, complementary growth hormone transcription signaling across distinct membrane receptors.
Ipamorelin Pathway (GHS-R1a Axis): Functions as a selective pentapeptide agonist of the Growth Hormone Secretagogue Receptor type 1a (ghrelin receptor). Upon binding, it couples to the Gαq/11 subunit, activating Phospholipase C (PLC), stimulating inositol 1,4,5-trisphosphate (IP3) and diacylglycerol (DAG) turnover, and triggering rapid mobilization of intracellular calcium ([Ca2+]i) without activating the non-specific release of ACTH, cortisol, or prolactin in cell cultures.
CJC-1295 Pathway (GHRHR Axis): Functions as a 29-amino-acid analog of Growth Hormone-Releasing Hormone (GHRH1--29), selectively binding the GHRH receptor. Coupling to the Gαs subunit stimulates adenylyl cyclase, elevating intracellular cyclic AMP (cAMP) and activating Protein Kinase A (PKA) to promote gene transcription of growth hormone (GH1).

Technical Laboratory FAQs
Why are Ipamorelin and CJC-1295 (No DAC) co-formulated in cell signaling research?
The blend allows researchers to model dual-receptor co-activation; Ipamorelin targets the Gαq-linked GHS-R1a receptor (calcium mobilization), while CJC-1295 activates the Gαs-linked GHRH receptor (cAMP pathway), demonstrating synergistic transcriptional kinetics in vitro.
How are both peptide components resolved and quantified in a single composite sample?
Reverse-phase HPLC (RP-HPLC) achieves baseline chromatographic separation between the smaller lipophilic pentapeptide Ipamorelin and the 29-residue tetrasubstituted CJC-1295, followed by electrospray ionization mass spectrometry (ESI-MS) to verify molecular identities at 712.4 Da and 3368.0 Da respectively.
What reconstitution vehicle is recommended for in vitro IPA/CJC assays?
Sterile deionized water or sterile PBS (pH 7.4) provides rapid dissolution for biological dilutions. For long-term stock stabilization against glutamine deamidation on the CJC-1295 peptide backbone, a dilute 0.1% sterile acetic acid solution is standard.
