Overview+

Thymosin Alpha 1 is a synthetic peptide identical to a naturally occurring thymic peptide. It is studied for its role in modulating immune-cell activity and is a frequent subject in immunological research, particularly work on how immune function can be reconstituted or regulated.

History+

First isolated from thymosin fraction 5 of calf thymus, Thymosin Alpha 1 was among the earliest thymic peptides to be sequenced and synthesized. Early research focused on its ability to help restore immune function in experimental models, and it has remained a reference peptide in studies of immune regulation.

PubChem ID: 16130571
Research findings+

Thymosin Alpha 1 has been studied in immune models for T-cell differentiation, dendritic-cell maturation, interferon and cytokine signaling, and Toll-like-receptor activity. Because it acts across both innate and adaptive arms of the immune system, Thymosin Alpha 1 is treated as a broad immunoregulatory probe rather than a single-pathway tool. Its identity with a natural thymic peptide is what keeps it a well-characterized reference in immunology research.

Key areas of research
  • →Immune: T-cell maturation, dendritic-cell signaling
  • →Signaling: Interferon, cytokine, TLR pathways
  • →Systemic: Innate and adaptive immune modulation

Frequently asked questions

What's the actual amount in each vial?+
Each vial contains the labeled mass of lyophilized peptide. Selected sizes appear above the price.
Are additional supplies needed?+
Reconstitution requires bacteriostatic water and appropriate sterile research labware – not included.
How long does a vial last?+
Sealed lyophilized vials are stable at −20°C for 24 months. Once reconstituted, store at 2–8°C and use within 28 days.
Does the product come with instructions?+
Each shipment includes the batch-specific Certificate of Analysis and recommended handling protocol.
What purity level is guaranteed?+
≥ 99% by reverse-phase HPLC (UV-220nm), confirmed via ESI-TOF mass spectrometry.
How should I store these products?+
Store sealed vials at −20°C, protected from light. Reconstituted solutions at 2–8°C.
What are peptides and how do they work?+
Peptides are short chains of amino acids that occur naturally in organisms, where they act as messengers in many biological systems. While some peptides have been developed for medical use, laboratory research focuses on understanding their activity at the cellular level, examining how they impact essential processes in vitro.
Do these products come with instructions?+
Products from Fast Track Labs are supplied without usage instructions, as they are designated solely for in vitro laboratory research and prohibited by law for human or animal consumption. Any misuse or unlawful application of these products will result in permanent denial of service.
How long do products take to deliver?+
Orders are typically processed and shipped within 24 hours, Monday through Saturday. Delivery times vary by location, but most domestic orders arrive within 3–5 business days. You'll receive tracking information as soon as your order ships.
