When sourcing Dihexa peptide for sale for biochemical, cellular, or animal model experiments, establishing analytical purity and structural verification is critical for experimental reproducibility. Dihexa (N-hexanoic-Tyr-Ile-(6)-aminohexanoic amide) is a synthetic, small-molecule peptide derivative developed to interact with the Hepatocyte Growth Factor (HGF) system. Researchers investigating neuroplasticity, synaptic formation, and receptor tyrosine kinase activation rely on high-grade material free from synthesis byproducts, TFA (trifluoroacetic acid) residues, and microbial contamination.
PX1 Research provides reference-grade Dihexa synthesized in domestic, GMP-compliant facilities. Designed strictly for in vitro assays and preclinical laboratory protocols, our catalog compounds undergo rigorous quality control to ensure that researchers receive precise, consistent material lot after lot. Academic and industrial laboratories can explore our complete line of target-specific reagents within our research peptides catalog.
Dihexa is an oligopeptide-derived small molecule with the chemical formula C27H44N4O5 and a molecular weight of approximately 504.66 g/mol. Unlike large recombinant neurotrophic factors such as Brain-Derived Neurotrophic Factor (BDNF) or native HGF—which exhibit poor stability, short biological half-lives, and limited tissue penetration—Dihexa was structurally designed as a stable, low-molecular-weight analogue capable of robust receptor binding affinity.
The molecular structure incorporates an N-terminal hexanoyl group linked to a dipeptide core (L-tyrosyl-L-isoleucine) and a 6-aminohexanoic amide terminus. This unique structural configuration confers enhanced metabolic stability against enzymatic degradation by aminopeptidases. In controlled laboratory environments, the compound remains stable across broad pH ranges, making it an ideal candidate for long-term cell culture studies and receptor binding kinetics assays.
The primary mechanism of Dihexa centers on its capacity to bind with high affinity to Hepatocyte Growth Factor (HGF) and facilitate its functional activation of the c-Met receptor (also known as the HGFR tyrosine kinase). Preclinical studies suggest that Dihexa acts as an allosteric potentiator, stabilizing the bioactive conformation of HGF and promoting c-Met dimerization and autophosphorylation.
Activation of the c-Met receptor tyrosine kinase initiates a downstream intracellular signal transduction cascade involving key pathways such as Phosphoinositide 3-kinase (PI3K)/Akt and Mitogen-Activated Protein Kinase (MAPK)/Extracellular Signal-Regulated Kinase (ERK). In vitro data indicate that these intracellular pathways regulate cellular survival, cytoskeletal remodeling, and the transcription of genes associated with synaptic architecture. Researchers studying receptor signaling mechanics often utilize compounds within the HGF/c-Met pathway peptides research hub to map cross-talk between growth factor receptors.
In vitro and ex vivo models have evaluated Dihexa for its capacity to induce spinogenesis—the formation of new dendritic spines—and promote synaptic strength. In primary hippocampal neuronal cultures, exposure to picomolar to nanomolar concentrations of Dihexa resulted in a statistically significant increase in dendritic spine density and dendritic arborization compared to vehicle controls.
Preclinical rodent models focused on cognitive impairment and neurodegenerative pathology have documented that Dihexa administration enhanced synaptic connectivity and restored long-term potentiation (LTP) in hippocampal slices. Furthermore, comparative assays show that Dihexa exhibits potency several orders of magnitude greater than recombinant BDNF in stimulating dendritic spine building in primary cell culture. For broader investigations into central nervous system repair pathways, scientists frequently cross-reference data from synaptogenesis compounds.
To understand the distinct operational mechanism of Dihexa, researchers frequently compare its biochemical profile against other synthetic neuroactive research compounds. While Dihexa targets the HGF/c-Met receptor system to directly drive structural spinogenesis, alternative compounds operate through distinct neuroendocrine or trophic pathways.
For instance, Semax is a heptapeptide derived from ACTH (4-10) that modulates brain-derived neurotrophic factor (BDNF) expression and monoaminergic neurotransmission, whereas Selank is a synthetic analogue of the immunomodulatory peptide tuftsin that interacts with GABAergic signaling. Additionally, compounds like Epithalon focus primarily on telomerase activation and cellular aging pathways rather than immediate synaptic structural remodeling. Comparing these distinct mechanisms allows laboratory teams to select the exact molecular pathway required for their experimental design.
Dihexa exhibits hydrophobic character due to its hexanoyl moiety and isoleucine residue, rendering its solubility characteristics different from standard hydrophilic peptides. Direct dissolution in purely aqueous buffers such as PBS or saline can result in precipitation or incomplete solubilization at higher stock concentrations.
For optimal laboratory preparation, researchers typically dissolve lyophilized Dihexa in organic solvents such as dimethyl sulfoxide (DMSO) or ethanol to create a concentrated primary stock solution (e.g., 10 mM to 50 mM). This primary stock can subsequently be diluted into sterile cell culture media or aqueous assay buffers, maintaining final organic solvent concentrations below 0.1% v/v to avoid cellular toxicity in cell-based assays. Reconstituted stock solutions should be aliquoted and stored at -80°C to prevent repeated freeze-thaw cycles.
Experimental integrity depends entirely on compound purity and batch consistency. PX1 Research subjects every batch of Dihexa to rigorous analytical testing in an ISO 17025-accredited laboratory environment prior to release.
Purity is quantified using Reverse-Phase High-Performance Liquid Chromatography (RP-HPLC), ensuring a chemical purity profile exceeding 98.0%. Molecular identity is verified via Electrospray Ionization Mass Spectrometry (ESI-MS), confirming exact mass alignment with calculated theoretical values. Additionally, because bacterial lipopolysaccharides can interfere with neural tissue culture models and receptor signaling assays, our Dihexa undergoes chromogenic Limulus Amebocyte Lysate (LAL) testing to confirm endotoxin levels remain strictly below <0.05 EU/mg. Certificate of Analysis (COA) documents per lot are available directly via our analytical research documentation hub.
PX1 Research manufactures all research compounds within the USA, adhering to strict Quality Management Systems (QMS) and GMP-aligned procedures. Lyophilized Dihexa vials are sealed under inert argon gas to protect against oxidative degradation and moisture absorption during transit.

Where can I buy verified Dihexa peptide for laboratory use?
Qualified researchers and institutional laboratories can purchase laboratory-grade Dihexa directly through PX1 Research. Every lot is manufactured in the USA, features third-party RP-HPLC and MS analytical reports, and is strictly designated for laboratory research use only.
What is the primary molecular target of Dihexa in research assays?
Dihexa acts primarily as an allosteric potentiator of Hepatocyte Growth Factor (HGF), binding HGF with high affinity to facilitate dimerization and activation of the c-Met receptor tyrosine kinase pathway.
What purity standard does PX1 Research guarantee for Dihexa?
PX1 Research guarantees that all Dihexa batches meet or exceed 98.0% chemical purity as measured by RP-HPLC, with molecular weight verified by ESI-MS and endotoxin levels tested below 0.05 EU/mg.
How should lyophilized Dihexa be stored upon arrival?
Lyophilized Dihexa powder should be stored at -20°C for short-to-medium-term stability or -80°C for extended storage. Desiccation protects the peptide from ambient humidity.
What solvent is recommended to reconstitute Dihexa for in vitro work?
