Buy Thymulin Research Peptide

Zinc-dependent biological activity sets Thymulin apart from all other thymic peptides, making it the only known endogenous thymic factor whose functional conformation is dictated by metal ion coordination. Also designated Facteur Thymique Serique or FTS (CAS 63958-90-7), carries a molecular weight of 952.21 g/mol as the zinc complex. Its sequence Pyr-Ala-Lys-Ser-Gln-Gly-Gly-Ser-Asn requires stoichiometric zinc binding for conformational integrity. Produced via solid-phase peptide synthesis.

In vitro studies using zinc-depleted and zinc-replete culture conditions have examined how zinc availability modulates the conformational equilibrium of FTS and its capacity to bind putative thymulin receptors on thymocyte surfaces. In vivo rodent models have investigated circulating Thymulin bioactivity using the rosette inhibition bioassay, examining how systemic zinc status correlates with serum FTS levels.
