Semax is a synthetic heptapeptide with the amino acid sequence Met-Glu-His-Phe-Pro-Gly-Pro (MEHFPGP). This compound is structurally derived from adrenocorticotropic hormone (ACTH), specifically containing the ACTH(4-7) fragment with an added C-terminal Pro-Gly-Pro tripeptide that enhances its stability and blood-brain barrier penetration capabilities.
Research Applications
Semax has been extensively studied for its potential properties including:
Neuroprotective mechanisms in cerebral ischemia models
Enhancement of cognitive function parameters
Neurorestorative activity in research models
Modulation of neurotrophic factor expression
Effects on brain-derived neurotrophic factor (BDNF) levels
Influence on default mode network activity Wikipedia
The compound has been the subject of numerous research papers investigating its role in learning processes, memory formation, and neuroprotection. Laboratory studies have examined its influence on various neuronal signaling pathways and gene expression patterns.
Storage & Handling Recommendations
Extreme Peptide’s Semax 5mg is provided as a lyophilized powder for maximum stability. For optimal compound integrity:
Store unopened vials at -20°C in a laboratory-grade freezer
Protect from light, moisture, and repeated freeze-thaw cycles
Reconstitute in sterile water (recommended minimum concentration: 100 µg/ml) prospecbio
Reconstituted solutions should be stored at 4°C and used within 7 days
For long-term storage of reconstituted solutions, add a carrier protein (0.1% HSA or BSA)
Aliquot reconstituted solutions to minimize freeze-thaw cycles
