Structural class
Thymulin is a zinc-dependent thymic nonapeptide (Glu-Ala-Lys-Ser-Gln-Gly-Gly-Ser-Asn) secreted by thymic epithelial cells and studied in T-lymphocyte differentiation assay models.
Pathways studied
Thymulin requires a 1:1 stoichiometric complex with Zn²⁺ for biological activity in receptor-binding and T-cell differentiation assays — the metal-free form (facteur thymique serique, FTS) is inactive. Upon Zn²⁺ coordination, thymulin promotes CD4/CD8 double-positive thymocyte maturation and the acquisition of T-cell receptor signalling competence. It has also been studied for modulation of inflammatory cytokine secretion profiles and NK cell activity in peripheral blood assay systems. Because circulating zinc levels determine the active/inactive ratio of endogenous thymulin, in vitro experiments must control Zn²⁺ concentration to produce interpretable results.
Typical research focus
Thymulin is used primarily as a thymopoiesis research tool and as a reference peptide for zinc-dependent peptide-receptor interaction studies. Comparative experiments using zinc-chelated (EDTA-treated) versus zinc-supplemented conditions allow researchers to toggle between inactive and active forms and cleanly attribute observed effects to thymulin rather than the zinc ion alone.

How to read a certificate of analysis, what purity actually measures, and how research peptides are stored and independently verified.
The questions researchers ask most.
Every batch is independently tested by Janoshik Analytical. Each product links straight to the lab's own record, so you can check the exact purity figure yourself before you buy — nothing to take on trust.
Keep vials sealed, dry, and out of direct light. Lyophilised (freeze-dried) peptides are stable at -20 °C; once reconstituted, store as noted on the product label. Full handling notes sit on every product page.
Order by 2pm for same-day dispatch from our Melbourne warehouse, otherwise the next business day, with tracked delivery Australia-wide. No customs, no border delays — it's already in the country.

Researchers who bought Thymulin also stock these.
It brings together 2 labelled variants: 5mg and 10mg, current pricing context, stock visibility, COA access, and internal links to related catalogue pages so a laboratory buyer can review the material from a single reference URL.
Thymulin is generally discussed as a zinc-dependent thymic nonapeptide (Glu-Ala-Lys-Ser-Gln-Gly-Gly-Ser-Asn) secreted by thymic epithelial cells and studied in T-lymphocyte differentiation assay models. The most relevant background is sequence behaviour, pathway or receptor context where documented, and analytical consistency under controlled laboratory conditions.
Use the label, COA, and internal SOPs as the primary guide. In general, store the material under controlled laboratory conditions, minimise avoidable environmental exposure, and keep variant tracking records current.
This page links the broader COA library when a product-specific document is not attached. Laboratories should use the published documentation set that is currently available for the listing.
No. The page should be interpreted strictly in a research and laboratory context. It does not provide dosage guidance, treatment claims, or human or animal use instructions.
