Semax is a synthetic heptapeptide built from a modified fragment of adrenocorticotropic hormone (ACTH 4–10), positioning it as a frequently used tool in laboratory research on neuropeptide signalling, receptor interactions, and peptide-mediated cellular communication.
Within biochemical and cellular research systems, Semax is applied to probe neuroendocrine signalling mechanisms and peptide-receptor interactions, with studies examining its influence on intracellular signalling pathways, transcriptional responses, and other neuropeptide-related processes. As with most peptide research, observed outcomes shift with concentration, exposure duration, assay methodology, and the model system in use.

Handling, Reconstitution & Stability
- Handle under dry conditions to minimise moisture exposure.
- Reconstitute using sterile water or an appropriate buffered aqueous solution according to experimental requirements.
- Avoid vigorous agitation during dissolution.
- Filter sterilize if needed (e.g. 0.22 µm) immediately prior to use.
- Aliquot and store reconstituted solutions at –20 °C (or lower) to avoid repeated freeze–thaw.
Precautions & Notes
- Experimental performance may vary according to peptide concentration, exposure duration, and model system utilised; appropriate positive and negative controls are recommended.
- Buffer composition, pH, and ionic strength may influence peptide stability and behaviour.
- Protect from prolonged exposure to moisture, light, and elevated temperatures.
- Experimental observations should be interpreted within the context of the specific assay system employed.
- Semax is intended exclusively for laboratory research and analytical applications. For research use only — not for human consumption, therapeutic use, diagnostic procedures, performance enhancement, or veterinary applications.
