Thymosin Alpha-1

Compound Overview

Thymosin Alpha-1 (Tα1) is a 28-amino acid peptide originally isolated from thymic tissue. In laboratory research, it is described as activating toll-like receptors (TLR2, TLR9), enhancing dendritic cell maturation, and stimulating T-cell differentiation. Controlled studies examine its role in innate and adaptive immune signaling.

Storage, Handling & Stability Guidelines

For long-term stability, store lyophilized Thymosin Alpha-1 material at -20°C. After reconstitution with sterile diluent, refrigerate at 2–8°C and minimize repeated freeze-thaw exposure by aliquoting working volumes according to your laboratory's standard operating procedures.

• Keep ambient-temperature handling time as short as practical to support compound integrity.
• Reseal vials promptly after each withdrawal to reduce moisture exposure.
• Use appropriate personal protective equipment and follow institutional chemical safety protocols at all times.
• For traceability, label all aliquots with compound name, concentration, reconstitution date, and operator initials.

Lab Verification

Nexus maintains batch-level verification records for research compounds in the Lab Verified archive, including HPLC purity review and Mass Spectrometry identity confirmation where current lot data is available.
