First isolated from calf thymus by Allan Goldstein and colleagues in 1977, Tα1 has been characterised in published research as one of the most-studied immunomodulatory peptides, with a body of literature spanning toll-like-receptor signalling, T-cell maturation and cytokine modulation in cell-culture and animal models.\u003c\/p\u003e\n\u003cp\u003eOptic Labs supplies Thymosin Alpha-1 in Australia as a lyophilised powder, 10mg per vial, third-party HPLC verified at \u0026gt;99% purity. The compound is provided strictly for laboratory research, including in-vitro innate-immunity assays, cell-culture cytokine-profiling work and animal studies of viral, oncological and immune-deficiency models.

TB-500 is a 17-amino-acid fragment of thymosin β-4, studied for actin-cytoskeleton remodelling, cell migration and tissue-repair pathways.
