Research overview

About this compound

Semax is a synthetic heptapeptide (Met-Glu-His-Phe-Pro-Gly-Pro). Its first four residues correspond to positions 4 to 7 of adrenocorticotropic hormone (ACTH), followed by a Pro-Gly-Pro tail that increases resistance to peptidases.

How it is used in research

It lacks the hormonal activity of full-length ACTH and is used in neuronal cell-culture and animal studies, including work on neurotrophin gene expression.

Analytical characterization

Synthetic peptides are usually characterized by reversed-phase high-performance liquid chromatography (HPLC), which reports purity as the share of the main peak, and by mass spectrometry, which confirms that the measured molecular mass matches the expected sequence. Results for a specific lot appear under Lab results once they have been posted.
