Mechanism of Action & Biochemical Context

Thymosin Alpha-1 (TA1) is a 28-amino acid peptide originally isolated from the thymus gland. FDA-approved as Zadaxin (internationally) for viral infections, it is a potent immune modulator that enhances T-cell maturation and immune response.

Storage, Reconstitution & Stability Guidelines

Prior to reconstitution, lyophilized Thymosin Alpha-1 powder should be stored away from light between 2°C and 8°C for short-term access, or -20°C for long-term preservation. Once reconstituted with Bacteriostatic Water (0.9% benzyl alcohol preservative), maintain strict refrigeration between 2°C and 8°C. Do not freeze liquid solution.
