What is TB-500?
TB-500 is a synthetic peptide corresponding to the actin-binding region of thymosin beta-4. Its interaction with actin makes it a common tool for studying cell migration and structural remodelling.
Key research applications
Cell migration
Actin-binding activity is used in motility and wound-closure assays.
Structural remodelling
Applied in connective-tissue and fibrosis endpoints.
Vascular models
Studied for new vessel formation alongside BPC-157.
