About
Selank is a synthetic peptide developed in Russia with anxiolytic (anti-anxiety), nootropic, and immunomodulatory properties. It is known for reducing stress without sedative effects.
Mechanism of Action
Selank modulates the expression of genes involved in inflammation and neurotransmitter systems. It increases the breakdown of enkephalins (the body's natural opioids), leading to an anti-anxiety effect. It also influences the levels of serotonin and dopamine and upregulates brain-derived neurotrophic factor (BDNF).
Key Benefits
- Reduces anxiety and stress without sedation
- Improves cognitive function, memory, and focus
- Modulates the immune system
- May have antiviral properties
Clinical Research
Developed at the Institute of Molecular Genetics of the Russian Academy of Sciences, Selank has been studied for its use in generalized anxiety disorder and as an immune modulator. It is approved for use in Russia and Ukraine.
Potential Side Effects
Selank has a high safety profile with minimal side effects. It is non-addictive and does not cause sedation or impair motor function.
Usage & Dosage
Typically administered as a nasal spray to bypass the blood-brain barrier effectively, or via subcutaneous injection. Research dosages vary.
Peptide Storage
Best Practices For Storing Peptides
To preserve the integrity of laboratory results, proper storage of peptides is essential. Correct storage practices can maintain peptides for years and guard against contamination, oxidation, and degradation. If the peptides will be used immediately, short-term refrigeration under 4°C (39°F) is generally acceptable. Lyophilized peptides are usually stable at room temperatures for several weeks.
For longer-term storage (several months to years), it is preferable to store peptides in a freezer at -80°C (-112°F). Avoid repeated freeze-thaw cycles and do not use frost-free freezers, as temperatures can fluctuate widely.
Preventing Contamination
To prevent moisture contamination, allow the peptide to come to room temperature before opening its container. Minimize exposure to air; after use, reseal the container under an atmosphere of dry, inert gas (like nitrogen or argon) if possible. Peptides with Cys, Met, or Trp are especially prone to air oxidation.
Storing Peptides In Solution
The shelf life of peptide solutions is far less than that of lyophilized peptides. If peptides must be stored in solution, use sterile buffers at pH 5-6 and separate into aliquots to avoid repeated freezing and thawing. Peptide solutions are generally stable for up to 30 days when refrigerated at 4°C (39°F).
