Thymosin Alpha-1 is the N-terminally acetylated, fully synthetic version of prothymosin α fragment 1–28 originally isolated from thymosin fraction 5 (TF5). For Research Use Only. Not for human use. This research-grade lyophilized peptide is produced under strict quality controls and provided with full analytical documentation, making it a reference compound for immunology, virology, and oncology research. According to published scientific literature, Thymosin Alpha-1 (thymalfasin) has been studied extensively as an immunomodulatory peptide; it has received regulatory approval in over 35 countries and has been granted FDA orphan drug designation for hepatocellular carcinoma and stage IV melanoma (fda.gov). It remains unapproved by the FDA and EMA for general therapeutic use in the United States and the European Union.
