Product information
Thymosin Alpha-1 — also referred to as TA-1, TA1, Tα1, and by the INN thymalfasin — is a synthetic 28-amino-acid N-terminally acetylated peptide corresponding to the amino-acid sequence of the endogenous thymic peptide first isolated and sequenced by the laboratory of Allan L. Goldstein (originally at Albert Einstein College of Medicine and later at George Washington University) from thymosin fraction 5. The peptide has an approximate molecular weight of 3108.3 g/mol and CAS number 62304-98-7. This product is supplied as a lyophilized powder at 10 mg per vial, synthesized by solid-phase peptide synthesis (SPPS) and characterized by HPLC (purity) and LC-MS (identity). It is intended exclusively for in-vitro laboratory research and analytical applications. In the research literature, Thymosin Alpha-1 is referenced as a synthetic peptide used as a tool compound in the study of Toll-like receptor pathways, particularly TLR9 and TLR2 signaling, and in comparative studies of thymic-derived peptides.
