How Thymosin Alpha 1 Works

Thymosin Alpha 1 is a naturally occurring thymic peptide that acts as an immunomodulator by enhancing T-cell maturation, differentiation, and function. It stimulates the production of Th1 cytokines (IL-2, IFN-gamma) while suppressing Th2 responses, activates dendritic cells and natural killer cells, and enhances antibody responses to vaccines. It signals through TLR2, TLR9, and TLR3 on dendritic cells and modulates the mTOR pathway for immune cell differentiation.

Reconstitution Calculator

Add this much bacteriostatic water:
5.0 mL
5 mg Thymosin Alpha 1 + 5.0 mL BAC water = 1 mg/mL

Inject bacteriostatic water slowly along the vial wall. Gently swirl until dissolved — never shake. Store reconstituted solution at 2-8°C and use within 30 days.

Frequently Asked Questions

Thymosin Alpha 1 (CAS: 62304-98-7) is a research compound, with a molecular weight of 3108.28 Da in the Healing / Recovery category. Thymosin Alpha 1 is a naturally occurring thymic peptide that acts as an immunomodulator by enhancing T-cell maturation, differentiation, and function. It stimulates the production of Th1 cytokines (IL-2, IFN-gamma) while suppressing Th2 responses, activates dendritic cells and natural killer cells, and enhances antibody responses to vaccines. Researchers commonly investigate Thymosin Alpha 1 for Hepatitis B and C treatment (approved in some countries), Cancer immunotherapy adjunct, Vaccine response enhancement. Every vial from MiPeptidos includes batch-specific analytical documentation.
Thymosin Alpha 1 is available in 2 sizes (5mg, 10mg), so reconstitution volume depends on which vial you have. For the 5mg size, add 1-2mL of bacteriostatic water; for the 10mg size, use 2-3mL. Always let the vial warm to room temperature first, inject the water slowly along the vial wall, and swirl gently — never shake. Store reconstituted Thymosin Alpha 1 at 2-8°C and use within 30 days. MiPeptidos carries bacteriostatic water in 3mL and 10mL vials.
Thymosin Alpha-1 (28 amino acids, 3108 Da) and Thymalin/Thymulin (9 amino acids, 859 Da) are both thymic peptides but target different immune pathways. Thymosin Alpha-1 activates TLR9 signaling and enhances dendritic cell maturation for adaptive immunity — it is approved in over 30 countries for hepatitis B. Thymalin acts through zinc-dependent thymulin pathways to modulate T-cell differentiation. MiPeptidos carries both for thymic immunology research.
Store lyophilized Thymosin Alpha 1 at -20°C for maximum long-term stability — properly stored, it remains potent for 24+ months. Once reconstituted with bacteriostatic water, keep it refrigerated at 2-8°C and use within 30 days. In research applications, Thymosin Alpha 1 has a reported half-life of ~2 hours, which informs dosing frequency and protocol design. Avoid repeated freeze-thaw cycles and protect from direct light. MiPeptidos ships every order with cold-chain packaging to maintain integrity during transit.
Every Thymosin Alpha 1 order from MiPeptidos includes a batch-specific Certificate of Analysis. Our current batch (HR-THYM-2600215, tested March 15, 2026) shows 99.7% purity by HPLC, mass spectrometry confirmation at 3108.28 Da, endotoxin levels below 0.1 EU/mg, and passing sterility per USP <71>. This level of documentation ensures you can verify compound identity and purity before beginning your research. MiPeptidos also offers bulk pricing on orders of 50+ vials — contact info@mipeptidos.com.
