Overview
Thymosin Alpha 1 functions as a potent immunomodulator influencing signaling dynamics, cytokine expression, and immune pathway homeostasis.
History
First isolated from bovine thymus gland in the 1970s by Allan Goldstein and colleagues.
Structure and mechanism
Thymosin Alpha-1 is a 28-amino-acid peptide with an N-terminally acetylated serine residue, originally isolated from thymosin fraction 5 — a partially purified extract of thymic tissue. The acetylation is not incidental: it is part of the defined structure and distinguishes the molecule from unmodified synthetic analogues of the same sequence.
It should not be confused with Thymosin Beta-4 or its fragment TB-500, which are structurally unrelated actin-binding molecules despite the shared 'thymosin' naming. In preclinical work Thymosin Alpha-1 is studied principally in immune-signaling models, including Toll-like receptor pathway investigation and T-cell maturation assays in cell culture.
Reconstitution and handling (research use)
Thymosin Alpha-1 is supplied as a lyophilized powder. For in-vitro laboratory use it is reconstituted with bacteriostatic or sterile water at a volume chosen to reach the target assay concentration. As a 28-residue peptide it is more susceptible to surface adsorption at low concentrations than shorter peptides, so low-binding labware is the usual choice for dilute working solutions.
Lyophilized material is generally stored at -20°C protected from light; reconstituted solution is refrigerated at 2-8°C and used within the study's defined window. This is general reagent handling guidance, not human or veterinary use instruction.
Wholesale sourcing notes
Thymosin Alpha-1 is the principal compound in the immune and inflammatory category and is commonly ordered alongside KPV and LL-37 by buyers building an immune-signaling panel. Material is sourced in the USA and independently verified by a third-party lab for identity, purity and quantitation.
Because the acetylated N-terminus is what distinguishes correctly synthesized Thymosin Alpha-1 from a cheaper unmodified analogue, the mass-spectrometry data on the Certificate of Analysis is worth reading rather than filing. A per-lot COA is included with every order at no charge, issued in the name of Wholesale Peptide Supply.

Thymosin Alpha 1 — Frequently Asked Questions
- What is Thymosin Alpha 1?
- Thymosin Alpha 1 functions as a potent immunomodulator influencing signaling dynamics, cytokine expression, and immune pathway homeostasis.
- What is the CAS number for Thymosin Alpha 1?
- The CAS number for Thymosin Alpha 1 is 62304-98-7. Its molecular formula is C₁₂₉H₂₁₅N₃₃O₅₅ (MW 3,108.28 g/mol).
- What doses of Thymosin Alpha 1 are available wholesale?
- Wholesale Peptide Supply stocks Thymosin Alpha 1 in 10mg. Wholesale pricing is provided by quote based on order volume, from a 3-kit (30-vial) order minimum, mix and match across doses and compounds.
- Is Thymosin Alpha 1 third-party tested?
- Yes. Every lot of Thymosin Alpha 1 is tested by an independent third-party laboratory, and a per-lot Certificate of Analysis documenting identity and purity is included with every order at no charge, issued in the name of Wholesale Peptide Supply. The most recent published lot, DPS-9015649 (10mg), was tested by Horizon Analytical on 14 September 2026 by UPLC/MS: purity 99.59%, endotoxin <0.05 EU/mL. Every lot on file is listed with its certificate on this page.
- Is Thymosin Alpha 1 for human use?
- No. Thymosin Alpha 1 is sold strictly as a chemical reagent for in-vitro laboratory research and is not for human or veterinary use. Wholesale Peptide Supply is not a pharmacy or compounding facility.
- How do I get wholesale pricing for Thymosin Alpha 1?
- Request a quote through our contact form or open a wholesale account. An account manager replies with volume pricing and lead times the same day. For anything urgent, text or call (714) 625-9215 to reach a real person in the US.
- Can I order Thymosin Alpha 1 in bulk?
- Yes. Thymosin Alpha 1 is available for bulk and wholesale orders, quoted by dose and volume, from a 3-kit (30-vial) order minimum, mix and match across doses and compounds, with lower prices at 10 kits and at 100 kits (1,000 vials) in the order. Submit the doses and quantities you need for a bulk quote.
- Is Thymosin Alpha-1 the same as TB-500?
- No. They share the word 'thymosin' but are structurally unrelated. Thymosin Alpha-1 is a 28-amino-acid acetylated peptide from thymosin fraction 5. TB-500 is a synthetic fragment of Thymosin Beta-4, an actin-binding protein. Different sequences, different molecular weights, different research literature, and not interchangeable in laboratory models.
- Why does the acetylation on Thymosin Alpha-1 matter?
- The defined structure of Thymosin Alpha-1 includes an N-terminally acetylated serine. An unmodified peptide of the same amino-acid sequence is a different molecule and will show a different mass on MS analysis. This is one reason the third-party Certificate of Analysis is worth reviewing on this compound in particular; it is included free with every order.
