Description
TA-1 (Thymosin Alpha-1) (Thymosin Alpha-1, Tα1) is a 28-amino-acid peptide originally isolated from thymic tissue. It is studied in immune-modulation research, including work on T-cell and innate-immune signaling.
What researchers study
- Immune-modulation research
- T-cell and innate-immune signaling
- Thymic-peptide models
Handling & storage
Supplied as a lyophilized powder for reconstitution with bacteriostatic water (not included). Store at −20 °C (−4 °F), protected from light. Every lot is independently tested against a 99%+ purity release target, and the batch Certificate of Analysis is published in full on this page.
Research Use Only (RUO). Not for human or animal consumption, nor for therapeutic, diagnostic, or cosmetic use; to be handled only by qualified professionals in a controlled research setting.
Identity and specification
TA-1 (Thymosin Alpha-1) is also referred to as Thymosin α1, Tα1 and Thymalfasin. It has the molecular formula C129H215N33O55 and a molecular weight of 3108.3 g/mol (CAS 62304-98-7).
How this lot was tested
Every lot is tested by an independent laboratory before release. Our published certificate library covers the lots currently in stock; if a certificate for this product is not yet listed there, email us and we will send the one for your batch.
We use two independent laboratories, and each certificate says which produced it. Vanguard Laboratory is ISO 17025:2017 accredited (A2LA certificate #6377.01.01) and reports chromatographic purity and net quantity with a stated measurement uncertainty. Freedom Diagnostics reports HPLC-UV purity together with LC-MS identity confirmation, which is what verifies the vial contains the compound on the label rather than merely a pure something. Two laboratories, two methods, both published — see how we test.
Commonly studied alongside
In the literature TA-1 (Thymosin Alpha-1) is most often examined together with Thymalin, BPC-157 and NAD+. Reconstitution is the same for all of them — see the reconstitution guide and the calculator, and the storage guide for how long reconstituted material holds. Current pricing for every compound and size is on the price list.
