Thymosin Alpha-1
A 28-amino-acid thymic peptide, Thymosin Alpha-1 (Tα1) is one of the most extensively studied immunomodulatory peptides in the literature. Each Vitalyx Bio vial contains 10 mg of Thymosin Alpha-1 as a lyophilized powder, supplied strictly for in-vitro and laboratory research.
Tα1 was originally isolated from thymic tissue as the active component responsible for restoring immune function in thymectomized research models. Its pleiotropic activity across T-cell, dendritic-cell, and innate-immune signaling has made it a key reference compound in immune-modulation research.
Mechanism of Action
- Toll-Like Receptor Signaling: Tα1 engages Toll-like receptors (TLR3/4/7/9) on myeloid and plasmacytoid dendritic cells, activating downstream IRF3 and NF-κB signaling pathways.
- T-Cell Differentiation: Research indicates Tα1 stimulates T-cell differentiation and enhances thymic output in immune-restoration models.
- Dendritic Cell & Macrophage Modulation: Investigated for its role in dendritic-cell maturation and macrophage activity, contributing to its pleiotropic immune profile.
Research Applications
- Immune Restoration Models: Studied in thymectomized and immunosenescence models for its capacity to restore T-cell function.
- Vaccine-Response Research: Investigated for its potential to improve vaccine response in aged research models.
- Innate Immune Signaling: Explored for its interaction with Toll-like receptor pathways across multiple immune-cell subsets, including T cells, B cells, macrophages, and natural killer cells.
Storage & Reconstitution
Keep the sealed, lyophilized vial cool, dry, and out of light, where it remains stable long-term before reconstitution. Reconstitute using sterile bacteriostatic water, directing the stream gently down the inside wall of the vial rather than onto the powder, and swirl — do not shake — until fully dissolved. Once reconstituted, store refrigerated at 2–8 °C, avoid freeze–thaw cycles, and follow your laboratory’s handling protocols.
This compound is strictly for in-vitro laboratory research use only and is not for human consumption, diagnostic, or therapeutic purposes.
