Product details
TB-500 — Thymosin Beta-4 Active Fragment
TB-500 is a synthetic 7-amino-acid fragment of Thymosin Beta-4 (Tβ4) corresponding to the actin-binding region of the parent protein. By isolating the bioactive core, TB-500 delivers the regeneration-associated activity of Tβ4 in a smaller, more readily synthesizable molecule, making it a workhorse peptide in soft-tissue and cardiovascular regeneration research.
Mechanism of Action
TB-500 binds monomeric G-actin through its conserved LKKTETQ motif, sequestering actin and influencing cytoskeletal dynamics during cell migration and matrix-remodeling research. Research has documented upregulation of laminin-5, increased endothelial progenitor cell mobilization, and accelerated reendothelialization after vascular injury. The fragment also interacts with paxillin and integrin-linked kinase pathways, which together support the formation of new capillaries and the organized remodeling of damaged extracellular matrix.
Research Applications
- Soft tissue and skeletal muscle regeneration studies
