TB-500 — Research Peptide

TB-500 is a synthetic peptide referenced in the scientific literature as an active fragment of Thymosin Beta-4 (Tβ4), a naturally occurring 43-amino-acid protein involved in actin-binding and tissue remodeling research. It is one of the most cited compounds within the regenerative pathway research peptide category. DISSOLV LABS supplies TB-500 as a 10 mg lyophilized vial — a high-purity analytical reference compound for qualified laboratory research professionals.

Purity: ≥99% (HPLC-MS verified)
Format: 10 mg lyophilized vial
Designation: Research use only — not intended for human or veterinary use

Compound Overview

TB-500 is a synthetic peptide derived from the actin-binding region of Thymosin Beta-4 — specifically the LKKTETQ amino acid sequence and surrounding residues that constitute the biologically active fragment in research literature. It is structurally and mechanistically distinct from body protection compound-derived peptides, copper-binding tripeptides, and α-MSH-derived fragments.

Within the published literature, TB-500 is frequently studied in laboratory work involving cellular migration, actin sequestration, and tissue remodeling pathway research. It is most commonly referenced alongside BPC-157, and the two are frequently combined into research stacks for comparative regenerative pathway studies.

Research Context

TB-500 has been investigated in published preclinical research and is commonly referenced in laboratory work involving:

• Actin sequestration and cytoskeletal remodeling research
• Cellular migration pathway models
• Angiogenesis and vascular endothelial pathway research
• Connective tissue and tendon biology research
• Comparative thymosin-family fragment structure–activity profiling
• Combination peptide research with body protection compound-derived peptides
• Tissue remodeling and extracellular matrix pathway research
