Thymosin β₄ Fragment (Residues 17–23) | Angiogenesis, Tissue Repair & Regeneration Research | For Research Use Only
TB‑500 is a synthetic peptide derived from the active region of Thymosin β₄, comprising the amino acid sequence N‑Ac‑LKKTETQ‑OH. This small fragment retains the key actin-binding domain of the parent peptide and is widely used in research on wound healing, angiogenesis, cell migration, and anti-inflammatory effects glpbio.com+8Peptide Sciences+8Science.bio: Driving Innovative Research+8.
Enhances Endothelial Cell Differentiation & Angiogenesis – Promotes new blood vessel formation
Accelerates Wound Healing & Tissue Repair – Stimulates keratinocyte and fibroblast migration
Anti-Inflammatory & Matrix Remodeling – Supports collagen deposition and reduces local inflammation
Promotes Hair Follicle Stimulation & Tissue Regeneration – Demonstrated in preclinical models
Superior Tissue Penetration vs Full-Length Thymosin β₄ – Shorter sequence increases bioavailability and diffusion
