Éclat de la peau › Mélange anti-âge 10 ml (4020 mg)

Skin Radiance – Anti-Age Blend is a multi-component research formulation, chemically an aqueous solution of two tripeptides, two free amino acids, and a dinucleotide cofactor. Within scientific research, the blend is studied as a model mixture for redox chemistry and metal coordination and as a reference mixture in analytical work. This formulation is offered as a ready-to-use liquid in a sealed 10 ml vial containing 4020 mg of dissolved components, exclusively for laboratory and research purposes.

What is Skin Radiance & Anti-Age Blend?

The formulation contains five compounds that differ significantly from each other chemically. Glutathione is a tripeptide with an unusual γ-peptide bond between glutamic acid and cysteine ​​and a free thiol group. L-histidine carries an imidazole side chain with a pK_a around 6, which coordinates metal ions. NADH is a dinucleotide with two phosphate groups and a reduced nicotinamide ring; glycine is the smallest and only achiral amino acid; GHK-Cu is glycyl-L-histidyl-L-lysine in complex with copper(II). This spread in polarity, charge, and molecular size makes the mixture a demanding test subject for separation methods.

In research models, two lines converge. The glutathione thiol and the nicotinamide ring of NADH are associated with in vitro systems in which the cellular redox state is monitored; the absorption band of NADH at 340 nm disappears upon oxidation to NAD.⁺ and forms the basis of countless enzyme analyses. In addition, GHK-Cu is a distinct coordination compound: the copper(II) ion is bound in a planar geometry, resulting in a dd transition in the visible region and giving the complex its own detection wavelength. Consequently, Skin Radiance 'Anti-Age Blend' is used as a model mixture and reference substance in scientific research.

Domaines de recherche

In a laboratory context, this blend occurs in the following research areas, among others:

• Analytical method development in which the mixture tests the selectivity and separation power of a chromatographic system.
• Multi-wavelength detection studies: the nucleotide bands around 260 nm, the NADH band at 340 nm, and the dd band of the copper(II) complex.
• Coordination chemistry research into the bond geometry and stability constant of copper(II) tripeptide complexes.
• In vitro research into the GSH/GSSG redox couple and thiol-disulfide equilibria under controlled conditions.
• Enzymological research in which NADH is monitored as a cofactor in cell-free assays.
• Stability study of thiols, nucleotides, and metal complexes side by side in the same aqueous solution.

Chacune de ces applications implique des recherches contrôlées en laboratoire ou sur des modèles précliniques.

Skin Radiance – Anti-Age Blend in our research range

This formulation falls under the blends category within our range: ready-to-use liquids containing multiple compounds in a single solution. Whereas individual compounds isolate a single target, a blend brings multiple classes into view simultaneously – in this case, a thiol-containing tripeptide, a metal complex, a dinucleotide, and two free amino acids. Other parts of the same product line are formulated around a different target and therefore contain different components.

Caractéristiques

Forme, manipulation et stockage

The blend is supplied as a ready-to-use, lightly coloured aqueous liquid in a sealed 10 ml vial; the material arrives in a dissolved state, so no further processing step is required. The colour cast is characteristic of the copper(II) complex. For analytical use, a sample is taken and processed according to the laboratory's own method.

Store the vial refrigerated at 2–8 °C, protected from light and heat, in the original packaging. Thiols and reduced nucleotides are sensitive to light, heat, and oxygen: keep the vial closed and limit how often it is removed from the refrigerator. Handle the material with standard laboratory precautions – clean environment, appropriate protective equipment, no cross-contamination – and keep the packaging out of reach of unauthorized persons.

Composition et résultats de laboratoire

Foire aux questions

To which fabric class does this blend belong?
Not a single compound, but an aqueous multicomponent formulation with two tripeptides, two free amino acids, and a dinucleotide cofactor. Therefore, a mixture does not have its own CAS number, molecular formula, or PubChem registration.

Why is the copper(II) component chemically special?
The copper(II) ion is bound in a planar geometry by the N-terminal amino group, an imidazole nitrogen, and a deprotonated amide nitrogen. This coordination yields a dd transition in the visible region.

In what form is the blend delivered?
As a ready-to-use liquid in a sealed 10 ml vial with 4020 mg of dissolved components.

Comment dois-je conserver la bouteille ?
Refrigerated at 2–8 °C, protected from light and heat, in the original packaging.
