Semax

Description

For Research Use Only. This product is supplied exclusively for laboratory research and is not intended for human or veterinary use.

Semax Research Peptide

Semax is a synthetic heptapeptide derived from the ACTH(4-7) sequence with a C-terminal Pro-Gly-Pro extension. ZENTRA supplies it as high-purity lyophilised research material in a 10mg format.

The published Semax sequence is Met-Glu-His-Phe-Pro-Gly-Pro (MEHFPGP). This page refers to standard Semax, not N-acetyl Semax or N-acetyl Semax amidate, which are chemically different compounds.

Technical Specifications

Independent Batch Testing

Every current ZENTRA Semax batch is independently tested and records an HPLC purity result above 99%. The batch number on the product label can be checked against the corresponding third-party report in our Batch Verification and COA Centre. Researchers should consult the individual report for the exact analytical methods, result and testing date for their supplied batch.

Semax Research Context

Published experimental work has investigated Semax in rat models involving BDNF/TrkB signalling, time-dependent Bdnf and Ngf gene expression, and gene-expression changes after focal cerebral ischaemia. Much of the Semax literature originates from Russian research groups, and independent replication and robust English-language human evidence remain limited.

These findings do not establish cognitive enhancement, neuroprotection, safety or an approved use in humans. Molecular and animal results should be described as research observations, not customer outcomes.

Storage and Handling

For long-term storage, keep unopened lyophilised material at approximately -20°C. For short-term laboratory storage, maintain at 2-8°C. Protect the vial from light, moisture and repeated temperature changes. Use appropriate laboratory handling procedures and consult your institutional protocol before preparing research solutions.

Semax Research FAQs

What is Semax?

Semax is a seven-amino-acid synthetic peptide derived from an ACTH fragment and extended with Pro-Gly-Pro.

What is the correct Semax CAS number?

The standard free-base Semax identity is associated with CAS 80714-61-0. The former number on this page was incorrect and has been replaced.

Is this N-acetyl Semax?

No. Standard Semax, N-acetyl Semax and amidated derivatives are distinct chemical identities and should not be treated as interchangeable.

Which size is available?

This product is supplied as 10mg of lyophilised research material.

How is purity verified?

Every current batch is independently HPLC tested above 99% purity with online batch-level COA verification.

Is this product intended for human or veterinary use?

No. It is supplied strictly for laboratory research and analytical purposes.
