What Is TB-500?

Research overview

TB-500 is a synthetic peptide based on Thymosin Beta-4, a naturally occurring actin-binding protein studied across cell-migration, angiogenesis, and tissue-repair research.

  • Synthetic fragment modeled on Thymosin Beta-4, a 43-amino-acid regulatory peptide
  • Studied for actin regulation, cell migration, and new-vessel formation
  • Frequently paired with BPC-157 in recovery-model research
  • Supplied strictly as a research-grade reference material

Research Applications

Studied in preclinical research models · not for human use

Tissue remodeling & wound models

Studied for re-epithelialization and cell migration in injury and wound-repair research.

Angiogenesis research

Investigated for its influence on new blood-vessel formation in preclinical models.

Cardiac & ischemic models

Examined for cell survival and repair signaling in models of ischemic injury.

Inflammation research

Explored for modulation of inflammatory signaling during tissue repair.

Proposed Mechanisms

Preclinical · proposed pathways

Actin sequestration

Binds and sequesters G-actin, a proposed basis for its effects on cytoskeletal dynamics and cell migration.

Angiogenic signaling

Associated in preclinical work with promotion of endothelial migration and new-vessel formation.

Cell survival pathways

Linked to integrin-linked kinase activation and reduced apoptosis in cardiac-injury models.

Anti-inflammatory modulation

Studied for down-regulation of inflammatory mediators during tissue remodeling.

Mechanisms described above are drawn from preclinical (cell and animal) research and, where noted, early clinical literature. They are provided for educational context and should not be read as clinical or therapeutic claims.

Frequently Asked Questions

TB-500
Is TB-500 intended for human use?
No. It is supplied strictly as a research-grade reference material for in-vitro and laboratory use, not for human or animal consumption.
How does TB-500 relate to Thymosin Beta-4?
TB-500 is a synthetic peptide based on the active region of Thymosin Beta-4, so the two are frequently discussed together in the literature.
What purity is the material?
Each batch is independently tested by an accredited U.S. laboratory and ships with a batch-specific Certificate of Analysis at greater than or equal to 99% purity by HPLC.
How is it stored?
Store lyophilized at -20°C; after reconstitution, refrigerate at 2-8°C and avoid repeated freeze-thaw cycles.
