Selank is supplied as a catalogued research material in 5 mg and 10 mg.

Selank is a defined seven-residue, tuftsin-derived peptide. The free peptide, N-acetyl analogue and acetate or TFA materials are not the same analytical article; sequence, termini and counter-ion must match the batch identity record [1,2].

Registry values apply only to the specific molecular entity, sequence, termini and material form. Batch records take precedence over family-level literature identifiers.

Selank is a synthetic heptapeptide developed in Russia, known for its anxiolytic, nootropic, and immunomodulatory properties. It is a fragment of the human immunoglobulin G (IgG) heavy chain.

Research background and published evidence

Published research

Published work supports cautious use in peptide-identity, degradation and rodent or cell-model gene-expression research, including exploratory GABA-related pathway analysis. A single validated direct receptor target has not been established [2,3].

Current scientific understanding

The literature is predominantly mechanistic, cellular and animal-model research and does not establish a human-use profile. Results for N-acetyl Selank, other salts or separately manufactured products must not be transferred to this batch.

Technical comparison

Aspect	This catalogue material	Comparator
Identity	Selank: TKPRPGP, a tuftsin-derived heptapeptide	Semax: MEHFPGP, an ACTH(4–7)-Pro-Gly-Pro peptide
Structural distinction	Thr-Lys-Pro-Arg N-terminal region followed by PGP	Met-Glu-His-Phe N-terminal region followed by PGP
Analytical implication	Use Selank-specific retention, mass and impurity references	Shared PGP terminus does not establish interchangeability

Quality and testing

Quality information is batch- and presentation-specific. Use only the report linked to the exact size and lot. A report listed for another size, lot or similarly named material must not be treated as evidence for this product.

Chromatographic area purity, identity, net peptide or analyte content, water or counter-ion content, sterility, endotoxin and elemental impurities are different measurements. One result does not establish the others. Only tests supported by a visible, matching report should be regarded as available.

Laboratory handling and storage

Store and handle only under the conditions stated on the product label, batch CoA and SDS. Keep the container secured, correctly identified and protected from contamination. Do not infer storage, solvent compatibility or stability from a related compound.

Laboratory preparation, analytical-method selection, risk assessment, personal protective equipment and waste disposal should follow the applicable SDS and the institution's approved procedures.

Regulatory and legal status

Frequently Asked Questions

Do the CAS number and PubChem CID apply to every batch form?

Only when the exact sequence or structure, termini, conjugation, salt or counter-ion and hydration state match. The batch CoA and SDS govern; a related-compound identifier must not be substituted.

What does an analytical purity result mean?

It is method- and report-specific. For example, an HPLC area percentage is not automatically the same as identity, net content, sterility, endotoxin status or absence of elemental impurities.

How should the material be stored and handled?

Follow the exact label, batch CoA and SDS together with the institution's risk assessment. Use only storage and stability information linked to the exact material form and batch.
