Analytical profile

Verified against PubChem, UniProt, ChEBI, regulatory labelling and peer-reviewed literature — not copied from another vendor's catalogue. Identity of the material actually shipped is confirmed per lot.

Written out
Semax: H-Met-Glu-His-Phe-Pro-Gly-Pro-OH · Selank: H-Thr-Lys-Pro-Arg-Pro-Gly-Pro-OH
Termini and modifications
Both: free N-terminus, free C-terminal acid, all L-residues. No terminal modification on either.
Residues
7
What it is
Semax: ACTH(4–7) extended with Pro-Gly-Pro — an analogue, since native ACTH continues Arg8. Selank: the native tetrapeptide tuftsin (IgG Fc residues 289–292) with the same Pro-Gly-Pro tail.

Worth knowing before you buy

A co-lyophilised blend of two peptides in one vial. Two components means two identity peaks and two net-content figures; a single number on a label cannot describe it, which is why the split per component is the figure to ask any vendor for.

Peptides of this class are supplied as acetate or trifluoroacetate salts, so gross powder weight exceeds net peptide content. The figure on our label and certificate is the peptide mass. What we test, and what we do not →

Description

Semax + Selank Nasal Spray is a blend of two synthetic heptapeptides supplied in a single vial.

  • Sequence — Semax · MEHFPGP (CAS 80714-61-0, C37H51N9O10S, 813.9 g/mol) | Selank · TKPRPGP (CAS 129954-34-3, C33H57N11O9, 751.9 g/mol)

Supplied as a lyophilized powder in a sealed glass vial. Store at −20 °C, desiccated and protected from light.

Peptides of this class are supplied as acetate or TFA salts, so gross vial weight exceeds net peptide content. The net content figure on our certificate is the peptide mass, measured gravimetrically.

Each lot is tested by an independent laboratory for HPLC purity and gravimetric net content. The report is published on this page and readable before purchase.

Described by identity only. For laboratory research use only — not for human or veterinary use, or any form of consumption.
