What it is
Thymosin alpha-1 (thymalfasin in drug nomenclature) is a defined thymic peptide. The catalog row is the lyophilized research material, not a finished-product claim.
Structure and sequence
Ac-Ser-Asp-Ala-Ala-Val-Asp-Thr-Ser-Ser-Glu-Ile-Thr-Thr-Lys-Asp-Leu-Lys-Glu-Lys-Lys-Glu-Val-Val-Glu-Glu-Ala-Glu-Asn.
Molecular weight
The reported mass of the acetylated 28-mer is 3108 Da.
What published research models study
The peptide was isolated from thymosin fraction 5 and studied in T-cell differentiation assays. Finished-product status differs by country. This note does not restate those assays as a use.
