RESEARCH OVERVIEW
What is Thymosin Alpha-1?
Thymosin Alpha-1 is derived from prothymosin alpha and was first isolated from thymosin fraction 5. It modulates innate and adaptive immune signalling, including toll-like receptor pathways and T-cell maturation.
Its literature covers immune ageing, infectious disease models and vaccine response research.

Thymosin Alpha-1 FAQs
Is Thymosin Alpha-1 for human use?+
No. Thymosin Alpha-1 is sold strictly for laboratory research use only. It is not a medicine, food supplement or cosmetic and must not be used in humans or animals.
How is Thymosin Alpha-1 tested?+
Each batch is tested for identity and purity by an independent laboratory using HPLC and mass spectrometry. Certificates are published on our Lab Reports page as each batch is released, and you can request the report for your batch at any time.
How should Thymosin Alpha-1 be stored?+
Lyophilised material should be stored sealed, dry and protected from light, ideally at -20°C for long-term storage. After reconstitution, laboratories typically store solutions at 2 to 8°C and avoid repeated freeze-thaw cycles.
How quickly will my Thymosin Alpha-1 order arrive?+
Orders placed before 2pm on a working day are dispatched the same day by Royal Mail Tracked 24. Delivery is free over £50, otherwise £4.99.
Do I need bacteriostatic water for Thymosin Alpha-1?+
Lyophilised peptides are supplied as dry powder. Laboratories reconstitute them with a suitable diluent such as bacteriostatic water, which we stock separately. Our reconstitution calculator works out the resulting concentration.
