Thymulin 20mg (10 Vials / Kit)

Thymulin at a glance

Thymulin was first described as serum thymic factor, or FTS from its French name, a substance in blood whose activity disappeared after removal of the thymus. It is a nine-residue peptide made by the thymus's epithelial cells, with the sequence pGlu-Ala-Lys-Ser-Gln-Gly-Gly-Ser-Asn. On its own the peptide is inactive; it gains biological activity only when it binds a zinc ion, a feature unusual among peptide hormones and central to how it is studied.

Price and availability

This is Uther Peptide‘s kit of 10 vials at 20mg each (200 mg in total), dispatched from China. $100.00 buys the whole kit, which is $0.50/mg. Uther Peptide is currently the only brand on the marketplace selling Thymulin. As with every order here, the brand is paid only after you confirm delivery.

What it is studied for

In its zinc-bound form, thymulin is thought to act on T-cell precursors in the thymus, promoting their maturation and the expression of markers that define functional T cells. Beyond the thymus, it has been reported to modulate immune and inflammatory signaling, including effects on cytokine production in animal models of inflammation and pain. Researchers also study links in the other direction, since hormones such as prolactin, growth hormone and thyroid hormone influence thymulin secretion. A specific receptor has not been firmly established.

Research and regulatory status

Thymulin research reaches back several decades in endocrine immunology. Blood levels of the active hormone fall with age as the thymus shrinks, making it a marker and focus in studies of immune aging, while other work covers zinc deficiency, autoimmunity and inflammatory pain models. Most experiments use rodents and cell systems. No thymulin-based drug has been approved, and data from controlled human studies remain limited.

Checking the lab data

The report should confirm the nine-residue sequence by mass spectrometry, taking into account the pyroglutamate at the N-terminus, and give HPLC purity with the chromatogram to compare against the stated purity of at least 99%. It should also say whether the material is the zinc-free peptide or a zinc complex, since that affects both mass and activity. Measured content per vial and a white freeze-dried cake should be documented.

Storage and preparation

Freeze-dried peptide keeps best sealed, cold and dark. Once it has been dissolved, refrigerate it, avoid repeated warming and follow the stability limits in your study protocol.

Concentration arithmetic: one 20 mg vial dissolved in 2 mL gives 10 mg/mL, or 20 mg/mL in 1 mL. The Research Lab calculator in your dashboard handles any other volume.
