Synthetic heptapeptide derived from tuftsin
COP 310.000
Selank is a seven-amino-acid research synthetic peptide derived from tuftsin, an immune-mediated peptide fragment. It is being studied in areas such as neuropeptide signaling, stress response, and memory in experimental models. It is supplied as a 10 mg vial of lyophilized powder, intended exclusively for scientific research.
Selank is a synthetic research peptide composed of seven amino acids (heptapeptide). Its structure corresponds to tuftsin, a peptide fragment naturally present in the body, linked to a stabilizing Pro-Gly-Pro sequence that prolongs its persistence in solution.
It is used as a reference compound in experimental models that study neuropeptide signaling, GABAergic activity, 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.
Selank is primarily studied in areas related to neuroscience and neuropeptide signaling:
– Stress response and anxious-type behavior in animal models
– GABAergic signaling and associated receptors
– Expression of neurotrophic factors (BDNF)
– Memory and learning processes in experimental models
– Tuftsin-associated immune modulation
