Active region of thymosin β-4 — regulates actin and cell migration in tissue repair.
Purity ≥98.7% HPLCFormat Lyophilized powderSKU TB-Research use only
Overview
TB-500 is a synthetic peptide corresponding to the active region of thymosin beta-4, a naturally occurring actin-binding protein involved in cell migration, cytoskeletal organization and tissue repair. In research models it is studied for its role in regulating actin dynamics, promoting angiogenesis and supporting cellular recovery.
Because of its small size and solubility, TB-500 is frequently investigated in tissue-repair and regeneration research. Supplied as research-grade material for laboratory use only.
Research applications
- Actin regulation and cytoskeletal dynamics
- Tissue-repair and wound-healing research models
- Angiogenesis and endothelial cell migration studies
- Flexibility, connective-tissue and recovery research
- Inflammatory modulation research
- Comparison with related regenerative peptides (BPC-157, etc.)

Open the calculator →Handling & storage
Supplied as a lyophilized powder. Store at 2–8 °C on receipt; protect from heat, light and moisture, and avoid excessive agitation. If reconstitution is required for laboratory work, use sterile technique — bacteriostatic water, or 0.6% acetic acid for low-solubility peptides. Protocols vary by research application.
