Oligopeptide-34
Also known as —
A synthetic oligopeptide associated with melanogenesis research, with limited sequence-resolved evidence for its molecular target.
- Length
- Commonly described as 13 amino acids; confirm against the sequence specification
- Half-life
- Not well characterised
- Mechanism
- Material described as Oligopeptide-34 has been associated with modulation of melanogenesis-related signalling and expression of pigmentation-associated proteins. A specific receptor target and a sequence-resolved molecular mechanism are not firmly established in the accessible research literature.
- Studied in
- Relevant laboratory models include cultured melanocytes and reconstructed pigmented epidermis, using melanin content, tyrosinase activity and melanogenic gene expression as separate endpoints.
About Oligopeptide-34
Oligopeptide-34 is a cosmetic ingredient designation used for a synthetic peptide commonly described as containing thirteen amino acids. The ingredient name alone is not an adequate analytical identity: the sequence, terminal modifications, counterion and purity should accompany each research batch. Public descriptions do not consistently provide these details, and a well-documented discovery history or a definitive relationship to an endogenous parent peptide cannot be assigned reliably from the name.
Its research context centres on pigmentation-associated cellular pathways rather than a firmly established receptor interaction. Melanocyte experiments can distinguish changes in melanin accumulation from changes in tyrosinase expression, enzyme activity or cell number. Measurements of MITF and related melanogenic markers may help characterise a response, but they do not establish direct target binding. Evidence obtained with multicomponent cosmetic preparations should not be attributed automatically to the isolated peptide.
Laboratory notes
- Require a sequence specification, mass-spectrometric identity result and chromatographic purity report before comparing batches.
- Establish solubility and solution stability experimentally; follow batch-specific storage instructions and minimise repeated freeze–thaw cycles.
- Pair pigmentation assays with viability and cell-number controls, and check for interference with absorbance-based melanin measurements.

Questions about Oligopeptide-34
Does Oligopeptide-34 have an established receptor target?
A specific receptor target is not firmly established. Changes in melanogenic markers should be reported as cellular observations rather than evidence of receptor engagement.
Does reduced cellular melanin demonstrate direct tyrosinase inhibition?
No. Cellular melanin can change through altered transcription, enzyme abundance, substrate availability or cell number. A separate cell-free enzyme assay is needed to investigate direct inhibition.
Is the ingredient name sufficient to reproduce an experiment?
No. Reproducibility requires the exact sequence, terminal chemistry, counterion, purity and formulation composition of the tested material.
Is Oligopeptide-34 for human use?
No. It is supplied strictly for in-vitro laboratory research and is not for human or animal consumption.
