Selank + Semax 5/5 mg

Selank + Semax for research: identity and specifications

Selank + Semax is a blend of two synthetic neuropeptides in a single vial: Selank (CAS 129954-34-3), a heptapeptide analog of tuftsin, and Semax (CAS 80714-61-0), a peptide derived from the ACTH(4-10) fragment. Supplied as a vial with 5 mg of each compound, lyophilized powder, with no fillers, carriers or excipients, at ≥98% purity by HPLC, made by SPPS and purified under analytical controls documented for every lot.

Scientific background

Selank, derived from the immunomodulatory tetrapeptide tuftsin, is investigated in experimental models for neuropeptide signaling and neurotransmitter modulation. Semax, an analog of the ACTH(4-10) fragment, is studied for its effect on the expression of neurotrophic factors such as BDNF and NGF in neuronal models.

Preclinical literature examines both compounds, alone or together, in neuronal cell culture and rodent models, focusing on distinct and potentially complementary neuropeptide pathways, always under controlled bench conditions and without extrapolating results to human or veterinary use.

• Neuropeptide signaling in cell culture
• BDNF and NGF expression in neuronal models
• Neuropeptide receptor interactions in vitro
• Complementary neuropeptide pathways in experimental models

Technical specifications

Analytical quality and chain of custody

Every lot of Selank + Semax is synthesized in registered facilities, with independent analytical verification by third-party laboratories and full chain-of-custody documentation. The certificate of analysis (COA) for each lot can be reviewed before purchase, recording HPLC purity and the other quality-control parameters used to release the material.

Reconstitution and laboratory handling

As a bench procedure, the lyophilized vial is reconstituted with a known volume of a suitable solvent, added along the inner wall of the vial, followed by gentle swirling until fully dissolved, without vigorous shaking. The reconstituted solution should be kept refrigerated and protected from light, and used in controlled assays within the stability period validated by the laboratory. Handling must be performed only by qualified personnel, in a bench environment suitable for in vitro experimentation, with lot number and storage conditions documented according to good laboratory practice.

Frequently asked questions

What is the purity of the blend supplied?
