Product Description

TB-500 is a synthetic version of the naturally occurring peptide Thymosin Beta-4 (Tβ4), a 43-amino acid protein present in virtually all human and animal cells. The active region of TB-500 is the N-terminal tetrapeptide Ac-SDKP, which has been the focus of extensive research in tissue regeneration, wound healing, and anti-inflammatory studies. Thymosin Beta-4 plays a central role in actin sequestration, cell migration, and blood vessel formation, making TB-500 a key compound in regenerative research.

Laboratory Product Information

📦 Includes

One (1) vial of TB-500 lyophilized powder (5mg per vial), Certificate of Analysis (COA).

🔬 Purpose

TB-500 is a synthetic form of thymosin beta-4, a 43-amino-acid actin-sequestering peptide found ubiquitously in eukaryotic cells. It is studied in in-vitro cell models for effects on G-actin polymerization dynamics, endothelial cell migration (scratch-wound assays), and angiogenesis-related gene expression.
