Description
The actin-binding active region of Thymosin Beta-4, studied for its role in cell migration and tissue remodelling.
Each lot is synthesised by solid-phase peptide synthesis, purified by preparative HPLC and released only after independent analytical testing. Supplied as a lyophilized powder in a sealed glass vial.
For laboratory research use only. Not for human or veterinary use.
TB-500 is used by investigators in the following research areas:
- Cell migration and actin-polymerisation assays
- Wound-healing and tissue-remodelling models
- Cardiac and skeletal muscle research
- Inflammation research
Information provided for laboratory research reference only.
The LKKTETQ motif corresponds to the actin-binding domain of Thymosin Beta-4. Research indicates it sequesters G-actin, influencing cytoskeletal dynamics that underlie cell motility and migration.
Information provided for laboratory research reference only.
- Defined, short sequence for reproducible studies
- N-terminal acetylation for stability
- Low molecular weight for easy handling
Information provided for laboratory research reference only.
TB-500 has been examined in a body of peer-reviewed preclinical literature. Researchers should consult primary sources for study design, models and findings.

Frequently Asked Questions
Handling, storage and documentation
Q01How should TB-500 be stored?
Store the lyophilized vial at -20°C, protected from light and moisture. After reconstitution, keep refrigerated at 2–8°C and use within the timeframe appropriate to your protocol.
Q02How do I reconstitute the vial?
Allow the vial to reach room temperature, then slowly add bacteriostatic water down the side of the vial and swirl gently — do not shake. Use our reconstitution calculator to plan concentrations.
Q03Where can I find the COA for my vial?
Match the lot number printed on your vial label with the certificate in the COA tab or in our COA library.
