TB-500 is a synthetic peptide fragment of Thymosin Beta-4 (Tβ4), a naturally occurring 43-amino-acid protein involved in cell migration, angiogenesis, and tissue repair signaling. TB-500 represents the active region of Tβ4 responsible for actin-binding and cell motility properties studied in preclinical research. Each batch is verified to ≥99% purity by third-party HPLC. Research Use Only.
TB-500 is a synthetic fragment of Thymosin Beta-4 containing the actin-binding domain (amino acids 17-23: LKKTETQ) that is central to Tβ4's proposed role in cell migration and tissue remodeling. Thymosin Beta-4 is one of the most abundant actin-sequestering proteins, and TB-500 replicates its experimentally relevant bioactive region.
Research applications include cell migration assays, wound healing biology, angiogenesis studies, cardiac tissue remodeling research, and comparative Thymosin Beta-4 pharmacology. TB-500 is used alongside BPC-157 in dual-peptide tissue repair research designs.
Every batch of TB-500 is synthesized using Solid-Phase Peptide Synthesis (SPPS) and purified via preparative HPLC to eliminate truncated sequences and synthesis byproducts. Final identity confirmation is performed via Electrospray Ionization Mass Spectrometry (ESI-MS), verifying exact molecular weight. Each lot ships with a Certificate of Analysis documenting purity exceeding 99%, giving researchers traceable, batch-specific verification before use in any laboratory protocol.
