## Pitch
Russian-origin synthetic tuftsin analog. Researched for anxiolytic-spectrum signaling, GABA pathway modulation, and neuroimmune regulation.

## Mechanism
Selank is a synthetic heptapeptide analog of the immunomodulatory peptide tuftsin, modified with a Pro-Gly-Pro extension. In vitro it modulates GABAergic and serotonergic systems and has anxiolytic activity in rodent models.

## Common in-vitro applications
### GABA-A receptor modulation
Ligand-binding assays + electrophysiology in cortical neuron cultures.
Working range: `0.1 µM to 10 µM`

### Cytokine modulation
IL-6 / TNF-α expression assays in stimulated PBMC cultures.
Working range: `1 µM to 100 µM`

## Researchers commonly co-treat with
- **Semax** — Pair Pro-Gly-Pro modified ACTH-derived peptide for parallel nootropic studies.

## Storage and handling
- Lyophilized: −20°C or below, desiccated
- Reconstituted: 2–8°C, use within 30 days
- Light + air: Protect from light and air
- Solubility: Soluble in bacteriostatic water (0.9% benzyl alcohol)
