Research Information
TB-500 is the synthetic version of thymosin β-4, a naturally occurring 43-amino-acid peptide, studied for its role in tissue research. Researchers are interested in how it interacts with actin — the protein that gives cells their structure and mobility — and in pathways involved in cell migration, angiogenesis (new blood vessel formation), and inflammation. Most published work has used in-vitro cell-migration assays and tissue-repair models to examine these mechanisms.
Research areas
- Actin sequestration studies
- Cell migration and chemotaxis research
- Angiogenesis pathway studies
- Inflammatory marker cell-model research
Analytical methods
Identity and purity are typically confirmed at source by high-performance liquid chromatography (HPLC) and mass spectrometry. All products are third-party tested for identity and purity.
Storage and handling
Store lyophilised at -20°C, away from moisture and direct light. Once reconstituted, store at 2–8°C and use within the timeframe specified on the source datasheet.
For Research Use Only. Not for human or veterinary use.
Third-party tested
All products are third-party tested for identity and purity.
