Dihexa 15mg — Vial Spec, Reconstitution Math & COA

Dihexa 15mg Mass Specification & Availability Overview

In standardized chemical research, a 15mg lyophilized vial of Dihexa (N-hexanoic-Tyr-Ile-(6-aminohexanoic acid) amide) yields 15.0 milligrams of high-purity small molecule peptide derivative. This quantitative mass is tailored for laboratory institutions executing extensive dose-response curves, cell-culture treatments, or enzymatic receptor assays requiring a uniform chemical lot. By standardizing on a single 15mg batch, analytical labs reduce run-to-run variability and minimize calibration overhead.

Please note: PX1 Research continuously updates its catalog based on manufacturing schedules and research demand. If a discrete 15mg lyophilized vial format is temporarily unavailable, researchers can access alternative research-grade configurations such as Dihexa Capsules 10mg for solid-state characterization, or explore our complete catalog of analytical standards via our all research peptides hub. Regardless of mass delivery format, all compounds undergo identical HPLC and Mass Spectrometry validation.

Solubilization Profiles & Reconstitution Calculations for 15mg Mass

Dihexa is an oligopeptide derivative characterized by an N-terminal hexanoyl group, imparting significant hydrophobic properties compared to classical hydrophilic peptides. Achieving complete solution homogeinity requires precise solvent selection. Initial solubilization typically utilizes dimethysulfoxide (DMSO) or ethanol as a primary carrier, followed by titration into sterile phosphate-buffered saline (PBS) or lab-grade water, depending on target assay cell toxicity tolerances.

When preparing stock solutions from a 15mg mass unit, volumetric accuracy determines final micromolar concentrations. The reconstitution table below outlines resulting stock concentrations across standard diluent volumes:

• Reconstituting with 1.0 mL diluent yields a final concentration of 15.0 mg/mL (15.0 µg/µL). • Reconstituting with 2.0 mL diluent yields a final concentration of 7.5 mg/mL (7.5 µg/µL). • Reconstituting with 3.0 mL diluent yields a final concentration of 5.0 mg/mL (5.0 µg/µL). • Reconstituting with 5.0 mL diluent yields a final concentration of 3.0 mg/mL (3.0 µg/µL).

Aliquot Planning and Working Solution Stability

Repeated freeze-thaw cycles degrade peptide structural integrity through localized micro-concentration and crystallization stress. For a 15mg batch size, lab managers should establish a clear aliquot strategy immediately following initial reconstitution. Dividing the 15mg stock into micro-aliquots (e.g., 50 µL to 200 µL in polypropylene low-binding microcentrifuge tubes) ensures that individual working stocks are thawed only once.

Reconstituted Dihexa in organic solvent/aqueous buffers should be stored at -20°C or -80°C for long-term stability studies. Working solutions kept at 2°C to 8°C should be consumed within 24 to 48 hours to prevent potential hydrolytic degradation or atmospheric oxidation.

Mechanistic Profile: HGF/c-Met Receptor Interactions in Preclinical Models

In preclinical literature, Dihexa is classified as a low-molecular-weight lipophilic compound studied for its high-affinity binding to Hepatocyte Growth Factor (HGF). Preclinical studies suggest that Dihexa binds to HGF with picomolar affinity, potentiating HGF-induced dimerization and phosphorylation of the c-Met receptor tyrosine kinase.

In vitro neuronal culture assays and rodent models demonstrate that c-Met pathway activation by Dihexa facilitates dendritic arborization and synaptogenesis. Unlike larger recombinant proteins, this synthetic hexapeptide fragment offers enhanced membrane permeability in cellular models, making it a critical reference compound in neurobiology research. Investigators studying synaptogenesis often cross-reference these findings in our central neuroscience research library.

Comparative Analysis: Dihexa and Related Nootropic Research Compounds

When evaluating neurogenic pathways in laboratory models, investigators frequently compare Dihexa to other synthetic oligopeptides designed for central nervous system research. Compounds in this comparative class differ fundamentally in their primary receptor targets and cellular mechanisms:

• Dihexa: Acts directly on the HGF/c-Met axis to stimulate dendritic spine formation and high-density synaptic connectivity in cultured neurons. • Semax: A heptapeptide derived from ACTH(4-10) that primarily modulates BDNF/TrkB expression and cholinergic transmission in rodent tissue models. • Selank: A synthetic analog of tuftsin that influences GABAergic signaling pathways and enkephalin stability in preclinical stress models. • P21: A synthetic peptide sequence derived from CNTF (ciliary neurotrophic factor) that acts on neurogenic differentiation pathways.

Understanding these distinct target profiles allows researchers to construct robust, controlled multi-compound matrix experiments.

Analytical Verification & Lot-Matched Certificates of Analysis

PX1 Research enforces strict quality control standards for every batch of research compounds distributed to laboratories. Each lot of Dihexa undergoes rigorous identity, purity, and safety verification at independent, ISO 17025 accredited testing facilities.

Our standard compliance protocol includes High-Performance Liquid Chromatography (HPLC) to confirm peptide purity (>98.0%), Mass Spectrometry (MS) to verify exact molecular mass, and chromogenic LAL assays to ensure endotoxin levels remain below strictly defined laboratory thresholds (<0.01 EU/mg). Researchers can instantly access and download raw analytical spectra for their active lot via our public Certificate of Analysis (COA) lookup tool.

Storage Parameters & Lyophilized Mass Handling

Unopened, lyophilized Dihexa vials should be stored at -20°C in a desiccated environment protected from light exposure. Under these conditions, the dry peptide mass maintains chemical stability for up to 24 months. If long-term storage exceeds two years, storage at -80°C under an inert gas headspace (such as argon or nitrogen) is recommended.

Before opening the vial for reconstitution, allow the container to equilibrate to ambient room temperature. Opening a cold vial exposes the dry cake to atmospheric condensation, which introduces moisture and can accelerate premature hydrolysis.

Selecting the Optimal Quantity: 15mg vs. Alternate Specifications

Choosing between a 15mg vial mass, smaller unit formats, or solid-state derivatives depends entirely on project scale and screening frequency. A 15mg specification is ideal for multi-week exploratory series, high-volume automated liquid handler plates, or shared core laboratory facilities. For smaller exploratory pilot assays, smaller unit masses reduce waste.

Conversely, research groups planning multi-phase clinical trial prep or large-animal preclinical models can request scaled production batches via our specialized wholesale lab account portal. PX1 Research provides flexible supply options to support research operations of all scales, backed by same-day shipping from our CA and AZ facilities.
