Thymosin Alpha-1

THYMOSIN ALPHA-1

Thymosin Alpha-1 is a natural regulator of immune function. Since its discovery in 1972—isolated from thymus gland tissue—it has been studied for its potential therapeutic role in a wide range of conditions, including:

  • Cystic fibrosis

  • Infectious diseases (e.g., tuberculosis, cytomegalovirus)

  • Respiratory disorders

  • Chronic hepatitis

  • Cancer

Thymosin Alpha-1 is recognized as a potent immune modulator, making it of high interest in both clinical and research settings.

Thymosin Alpha-1 (often called Tα1) is a short, naturally inspired peptide that researchers use to explore how the immune system “switches on” and coordinates its response. In simple terms, it’s a tool for studying signaling that helps the body recognize challenges and organize both innate and adaptive defenses in controlled models.

In research literature, Tα1 is discussed around T-cell support, dendritic cell activation, and pattern-recognition pathways (e.g., toll-like receptor signaling) that shape cytokine balance and antigen presentation. Teams look at readouts like T-cell maturation/activation markers, dendritic cell function, and downstream cytokine profiles to map how immune tone shifts under defined conditions. These are research signals, not medical outcomes, and results vary by model and protocol.

What sets our Thymosin Alpha-1 apart is verified quality. Each batch is identity-confirmed (e.g., mass spectrometry) and purity-checked by HPLC, delivering ≥99% purity (typical). You receive a lot-specific Certificate of Analysis (COA) with real test data—clear proof you can read and cite in your records.

We prioritize repeatable consistency. Specifications are kept tight from batch to batch and every lot is tracked, so when you reorder you can match the same analytical fingerprint—useful for method development, comparisons, and follow-up work where consistency is as important as the initial result.

If you value clarity, documentation, and high purity for immunology research, Thymosin Alpha-1 from AI Peptides delivers exactly that—well-characterized material with transparent proof, so you can focus on the science with confidence.

Not for human or veterinary use. Made in USA

This product is intended as a research chemical only. Not for human use. Peptides will arrive in a lyophilized (powder) form for maximum stability.

Storage Instructions:

All of our products are manufactured using the Lyophilization (Freeze Drying) process, which ensures that our products remain 100% stable for shipping for up to 3-4 months.
Once the peptides are reconstituted (mixed with bacteriostatic water), they must be stored in the fridge to maintain stability. After reconstitution, the peptides will remain stable for up to 30 days.

Lyophilization is a unique dehydration process, also known as cryodesiccation, where the peptides are frozen and then subjected to low pressure. This causes the water in the peptide vial to sublimate directly from solid to gas, leaving behind a stable, crystalline white structure known as lyophilized peptide. The puffy white powder can be stored at room temperature until you’re ready to reconstitute it with bacteriostatic water.

Once peptides have been received, it is imperative that they are kept cold and away from light. If the peptides will be used immediately, or in the next several days, weeks or months, short-term refrigeration under 4C (39F) is generally acceptable. Lyophilized peptides are usually stable at room temperatures for several weeks or more, so if they will be utilized within weeks or months such storage is typically adequate.

However, for longer term storage (several months to years) it is more preferable to store peptides in a freezer at -80C (-112F). When storing peptides for months or even years, freezing is optimal in order to preserve the peptide’s stability.
