Description
Thymosin Alpha-1 is a research material commonly used as a reference standard or experimental reagent in controlled laboratory settings. Typical use cases include TLR signaling assays, T-cell and dendritic cell differentiation studies, cytokine profiling, analytical method development, and non-clinical workflows.
Marketed as thymalfasin (Zadaxin) in a number of countries for hepatitis B and C and as an adjuvant in other indications, it has not received FDA approval in the United States. Regulatory status therefore varies substantially by jurisdiction — relevant if you are sourcing or shipping internationally.
Documentation such as COA, HPLC chromatograms, and LC-MS data may be available on a lot basis where applicable. Request documentation by emailing connect@novuspeptides.com with the catalog number and required tests.
This product is sold strictly for laboratory research use only and is not intended for human or veterinary administration. Buyer is responsible for lawful handling, storage, and use in accordance with all applicable regulations.
