CNS Research Peptides

Synthetic peptides studied in vitro in neurochemistry, receptor-binding and neurotrophic-signalling assays. All three came out of Russian research programmes of the 1980s and 1990s, which is why the published literature on them is comparatively deep for this category.

Semax is a modified ACTH(4-10) fragment carrying a C-terminal extension that resists enzymatic cleavage, and appears in BDNF and NGF transcription studies. Selank is a stabilised tuftsin analogue studied in GABAergic modulation and cytokine-expression assays. DSIP is a nine amino acid peptide first isolated during sleep-physiology research and studied in EEG-pattern and HPA-axis models.

All three are supplied as lyophilised powders. Solubility and stability differ between the sequences, so each product page gives the diluent and handling conditions for that compound rather than a single figure for the category.

Every vial carries an independent certificate of analysis, HPLC purity and mass spectrometry identity, batch-matched to the vial supplied.
