Selank is a synthetic seven-residue peptide with the sequence Thr-Lys-Pro-Arg-Pro-Gly-Pro. This listing is for an in-vitro laboratory research material. Our Selank guide to human studies, mechanisms and safety explains what the experiments measured and how their findings differ from everyday anxiety or cognition claims.

Compound Overview

Selank extends the four-residue tuftsin sequence, Thr-Lys-Pro-Arg, with Pro-Gly-Pro. Research examines several distinct endpoints, including GABA-related binding and gene expression, peptide degradation, immune-cell measurements and behavior in animal models. These findings depend on the system and conditions; they do not establish one universal receptor mechanism or a predictable human effect.

Research Background & Published Literature

The published record includes small human anxiety studies as well as cell and animal experiments. For example, a 2014 open randomized comparison examined Selank and phenazepam, while a human-derived neuroblastoma-cell experiment found no measured neurotransmission-gene change with Selank alone. Those are different questions and evidence levels. The standalone guide distinguishes the clinical observations, their design limitations and the mechanistic null findings.

Researchers interested in the published literature surrounding this compound can explore the following peer-reviewed resources for additional context on its mechanism of action, signaling pathways, and experimental applications in controlled laboratory settings:

Technical Specifications

  • Analytical results: Read the applicable report for its configuration, methods, results and reporting limits.
  • Physical Form: Lyophilized (freeze-dried) powder
  • Intended Use: In-vitro research use only — not for human consumption

Storage, Handling & Stability Guidelines

Use the applicable product label and your laboratory’s validated procedure for storage and solution preparation. A molecular identity or chromatographic result does not establish a solution shelf life. Record the actual handling conditions and assess suitability for the intended assay.

  • Check the labeled storage conditions before receipt and handling.
  • Document the solvent, concentration and preparation time used in the experiment.
  • Follow institutional chemical-safety procedures and use appropriate protective equipment.
  • Keep the compound, configuration and lot identifier with each prepared sample.

Quality Assurance & Analytical Verification

A published analytical report describes its identified sample and the methods used for that record. Read the applicable report in the batch panel or COA library, matching the compound, configuration and lot to your material. Chromatographic purity, identity and peptide content are different measurements; the record does not by itself establish the results for a later order, biological activity or sterility.

Frequently Asked Questions

What is the primary research application of this compound?

Selank is studied through questions about its tuftsin-related sequence, GABA-related measurements, immune-cell endpoints and behavior. Select the exact model and endpoint for the experiment; a clinical or animal finding is not automatically a property of the material in an in-vitro assay.

What storage conditions are recommended?

Follow the applicable label and a validated laboratory procedure. Storage and solution stability depend on the material, formulation and conditions; this page does not establish a general post-preparation lifetime.

Is this product approved for human use?

No. This product is supplied as an in-vitro laboratory research reagent, not a finished medicine for human or veterinary use. It should not be treated as interchangeable with a clinical study formulation.

What documentation is available for this compound?

Consult the applicable published record in the Lab Verified archive, checking its named compound, configuration, lot and methods. For a specific documentation question, use our contact page. Do not assume that every record contains the same tests or establishes the identity of a later shipment.

Is bulk ordering available?

For a quantity or packaging inquiry, contact the team with the compound name, desired amount, preferred configuration and target timeline. Confirm current availability, pricing and any special requirements before ordering.
