Semax 10 mg

Synthetic ACTH analogue heptapeptide (4-10)

COP  310.000

Semax is a seven-amino-acid research synthetic peptide derived from a fragment of adrenocorticotropic hormone (ACTH 4-10) with no hormonal activity. It is being studied in areas such as neuroprotection, the expression of neurotrophic factors, and attention and memory processes in experimental models. It is supplied as a 10 mg vial of lyophilized powder, intended exclusively for scientific research.

Semax is a synthetic investigational peptide composed of seven amino acids (heptapeptide). Its structure corresponds to the 4-10 fragment of adrenocorticotropic hormone (ACTH), linked to a stabilizing Pro-Gly-Pro sequence. This modification eliminates the hormonal activity of the original fragment and prolongs its persistence in solution.

It is used as a reference compound in experimental models that study neuroprotection, synaptic plasticity, and the expression of neurotrophic factors.

At KaiLab, peptides are supplied as a freeze-dried powder intended exclusively for scientific research. It is not approved for human or veterinary use.

These recommendations apply to all KaiLab freeze-dried peptides.

Freeze-dried powder (not reconstituted):
– Store at −20 °C for long-term storage.
– Protect from light and keep in a dry environment.
– Under these conditions it maintains its stability for extended periods.

Reconstituted (in solution):
– Reconstitute routinely with bacteriostatic water, under laboratory conditions.
– Store refrigerated (2°C to 8°C).
– Avoid repeated freezing and thawing cycles.
– Handle with aseptic technique and appropriate laboratory equipment.

These instructions pertain solely to the handling of research materials.

Semax is primarily studied in areas related to neuroscience and cognitive function:
– Neuroprotection in ischemia and hypoxia models
– Expression of neurotrophic factors (BDNF and NGF)
– Attention, learning and memory in experimental models
– Synaptic plasticity and neuronal signaling
– Response to oxidative stress in nervous tissue
