Research use

For laboratory research use only. Not for human or veterinary use.

Mechanism of action

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.

Research applications

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.
