Research Overview
TB-500 is a synthetic version of the active 17-amino-acid region of thymosin beta-4 (Tβ4), a naturally occurring polypeptide present in nearly all human and animal cells. TB-500 is widely used in laboratory research focused on actin sequestration, cell migration, and tissue regeneration.
Mechanism of Action
TB-500 binds G-actin monomers and influences cytoskeletal dynamics. In research models this has been linked to enhanced endothelial and keratinocyte migration, supporting angiogenesis and re-epithelialization studies.
Research Applications
- Actin sequestration assays
- Cell migration / wound-closure research
- Endothelial and keratinocyte studies
