Overview
A research formulation pairing Semax, an ACTH(4-10) analog, with Selank, a tuftsin analog. Both are Russian-developed regulatory peptides and are frequently studied side by side in neuropeptide research.
History
Combines two peptides from the same Russian regulatory-peptide research program — one derived from ACTH(4-10), the other from the immunomodulatory tetrapeptide tuftsin — supplied together for comparative and combined-pathway work.
Two Russian regulatory peptides, two different parents
This blend pairs Semax and Selank, which are routinely mentioned in the same breath because both emerged from the same body of Soviet and Russian peptide research. They are not variations on one another.
Semax is an analogue of ACTH(4-10) — a fragment of adrenocorticotropic hormone with the hormonal activity engineered out and the neuroactive fragment retained. Its research sits in neurotrophic signalling: BDNF and NGF pathway activity and the cascades downstream of them.
Selank is an analogue of tuftsin, a tetrapeptide fragment of the immunoglobulin heavy chain. Its lineage is immune rather than endocrine, and the signalling studied around it reflects that.
So the blend combines two distinct parent molecules from two distinct systems, which is exactly why combined-versus-single-peptide comparative models exist for it: the question is whether the two pathways interact or simply run in parallel. Both components are also stocked individually for that reason.
Supplied lyophilised; stored at -20°C protected from light, reconstituted solution refrigerated at 2-8°C. General reagent handling guidance only.
