Characterization

What it is, stated plainly.

What it is

A synthetic heptapeptide, Met-Glu-His-Phe-Pro-Gly-Pro: the ACTH(4–7) fragment extended at the C-terminus with Pro-Gly-Pro, an extension that resists peptidase cleavage. It has no melanocortin-receptor activity of the kind full-length ACTH has, and NO DEFINED RECEPTOR HAS BEEN ESTABLISHED FOR IT. Published mechanism work concerns neurotrophic signalling; it sits in the neuropeptide literature.

How a lot is verified

Identity confirmed by HPLC and mass-spec; purity assayed by third-party HPLC, with a certificate of analysis published where tested. A lot that misses spec is rejected.

Handling & storage

Supplied as a lyophilized powder. Store at −20°C, desiccated and protected from light. Handled per the receiving laboratory's protocols. Not for human consumption.

Also known asACTH(4-7)-Pro-Gly-Pro · MEHFPGP · ACTH (4-10) heptapeptide analog

Semax is a synthetic heptapeptide (Met-Glu-His-Phe-Pro-Gly-Pro) modeled on a fragment of adrenocorticotropic hormone (ACTH 4-7) extended with a Pro-Gly-Pro tail, supplied as a lyophilized powder for laboratory research use only.

In the literature it is studied in neurochemistry research models and for its metal-ion (copper / zinc) coordination chemistry; the characterization here reflects that research literature only.

Reported mechanism · literatureStudied in the research literature in the context of melanocortin-related signalling and neuromodulation models; the summary reflects that literature only.

Questions

Answered straight.

What is Semax?

Semax is a synthetic heptapeptide derived from an ACTH(4-7) fragment with a Pro-Gly-Pro extension. Ouralus supplies it as a lyophilized powder for laboratory research use only, with a third-party HPLC certificate of analysis published where tested.

What is the sequence of Semax?

The base Semax heptapeptide is Met-Glu-His-Phe-Pro-Gly-Pro (free acid), molecular formula C37H51N9O10S (PubChem CID 9811102, CAS 80714-61-0). An N-acetylated variant is a distinct related compound.

Who can order?

These materials are supplied strictly for laboratory and research use, to purchasers of legal age. They are not supplements, drugs, or foods, and are not for human or animal consumption.

Is Semax legal to buy?

Semax is supplied strictly as a research chemical for laboratory research use only — it is not a drug, supplement, or food, and not for human or animal consumption. It ships to purchasers of legal age for research use. Buyers are responsible for compliance with the laws that apply to research materials in their own jurisdiction.

Is a certificate of analysis provided with Semax?

Yes — each tested lot of Semax ships with a third-party HPLC certificate of analysis from Janoshik, independently verifiable by lot (verify key LI1FR3Y5KSVB). The current lot assayed 99.184%. We publish the certificate before making any purity claim; this is a research chemical for laboratory use only.
