Purity and Laboratory Testing

Lot AFL-TA1-10-2026-001 (tested 2026-04-24) of Thymosin Alpha-1 was assayed by an independent laboratory using reversed-phase HPLC for purity and mass spectrometry for identity confirmation, returning 99.4% purity. The Certificate of Analysis shipped in the box matches the lot number printed on the vial.

Technical Product Information

Molecular formula C₁₂₉H₂₁₅N₃₃O₅₅, molecular weight 3108.29 g/mol, sequence Ac-Ser-Asp-Ala-Ala-Val-Asp-Thr-Ser-Ser-Glu-Ile-Thr-Thr-Lys-Asp-Leu-Lys-Glu-Lys-Lys-Glu-Val-Val-Glu-Glu-Ala-Glu-Asn-OH. Tα1 activates dendritic cells and T-cell maturation via TLR-9 and TLR-2 signaling. It increases Th1 cytokine production (IL-2, IFN-γ), upregulates MHC class I expression and shifts the immune response toward cell-mediated immunity — relevant to viral infection, sepsis and immunocompromised states. Thymosin Alpha-1 is supplied as lyophilized powder and is classified in our catalog under thymic hormone for thymic hormone work. Recorded research categories for this compound include antiviral immune response research, hepatitis b and c research, vaccine adjuvant studies, sepsis and immunosuppression research. Handling notes: store at -20°c (freezer), protect the vial from light, and avoid repeated freeze–thaw cycles once reconstituted. Amino Fuel Labs publishes no dosing protocol for Thymosin Alpha-1: the compound is distributed for in-vitro and preclinical laboratory research only and is not intended for human or veterinary use.

Frequently Asked Questions

Is Thymosin Alpha-1 the same as Zadaxin?

Yes. Zadaxin is the brand name for pharmaceutical Thymosin Alpha-1, approved in 35+ countries for hepatitis B, hepatitis C and as an immunoadjuvant. Same molecule, same sequence.

What's the difference vs TB-500 (Thymosin Beta-4)?

Tα1 and Thymosin Beta-4 are unrelated despite the shared 'thymosin' name. Tα1 modulates adaptive immunity; TB-500 is studied for tissue repair and angiogenesis.

Is Tα1 stable at room temperature?

Lyophilized vials are stable at room temperature short-term but should be refrigerated for long-term storage. Reconstituted product must be refrigerated.

What is Thymosin Alpha-1 studied for?

Thymosin Alpha-1 appears in laboratory research covering cancer immunotherapy, viral infections, vaccine enhancement. All references describe in-vitro and preclinical study models only.

Does Thymosin Alpha-1 include a Certificate of Analysis?

Yes. Each Thymosin Alpha-1 lot ships with a batch-specific third-party Certificate of Analysis reporting 99.4% purity by reversed-phase HPLC alongside mass-spectrometry identity confirmation.

What form does Thymosin Alpha-1 arrive in?

Thymosin Alpha-1 is supplied as lyophilized powder in a sealed vial, packed with the lot documentation for the exact batch shipped.
