TB-500 10mg 3 Vials: Thymosin Beta-4 Fragment

TB-500 is a synthetic research peptide designed to replicate the active regenerative region of the naturally occurring protein Thymosin Beta-4 (Tβ4). This peptide fragment is widely studied for its potential role in cell migration, tissue repair, angiogenesis, and inflammatory modulation within controlled research environments.

Its small size and enhanced stability make TB-500 a preferred investigative form of the Tβ4 pathway in experimental models.

Scientific Background

Thymosin Beta-4 is a 43-amino-acid peptide found throughout mammalian tissues, with high concentrations in platelets, skin, muscle, and the central nervous system. TB-500 is based on the LKKTET amino-acid sequence — the portion of Tβ4 most strongly associated with:

• Actin regulation
• Cellular motility
• Tissue regeneration
• Blood vessel formation

By focusing on this functional region, TB-500 allows researchers to explore Tβ4-linked biological pathways with improved stability and simplified manufacturing.

Research Areas of Interest

1. Tissue Repair & Regeneration

TB-500 is evaluated in preclinical models for its potential to support:

• Cellular migration to injury sites
• Fibroblast activation
• Tissue remodeling and repair
• Accelerated wound closure

2. Angiogenesis

The Tβ4/TB-500 pathway is known to promote:

• Endothelial cell movement
• Capillary formation
• Blood-vessel growth in damaged tissue

3. Anti-Inflammatory Properties

Investigational studies highlight possible reductions in:

• Pro-inflammatory cytokines
