An introduction to Semax, a heptapeptide ACTH(4-10) analog reference material studied in neuropeptide research.
What it is
Semax is a synthetic heptapeptide and an analog of the ACTH(4-10) sequence, supplied strictly as a research-use-only reference material. It is catalogued under the neuropeptide category and identified analytically by CAS number 80714-61-0 and a molecular weight near 813.9 g/mol with a purity specification of not less than 98% by HPLC.
Relationship to ACTH(4-10)
Semax derives from the ACTH(4-10) fragment, modified with a Pro-Gly-Pro tail at the carboxyl terminus. This terminal extension is a defining structural feature that distinguishes the analog from the native fragment and is associated with greater resistance to enzymatic breakdown in research settings.
