What Researchers Look For

Thymosin Alpha-1 is a 28-amino acid N-terminally acetylated peptide with a molecular weight of approximately 3108 Da. Researchers should verify both HPLC purity and mass spectrometry molecular weight, with specific attention to the N-terminal acetylation, which is an essential feature of the authentic compound and not present in all commercially available synthetic versions. The acetylation is required for full TLR activation activity as documented in the published literature.

Why Spartan Peptides

Spartan Peptides supplies N-terminally acetylated Thymosin Alpha-1 at a minimum 98% HPLC purity with batch-specific certificate of analysis. The authentic acetylated structure matches the pharmaceutical reference compound (Zadaxin) used in the clinical trial literature. US domestic dispatch supports fast receipt for ongoing immune research programs.
