TB-500 (Thymosin Beta-4)
TB-500 is a synthetic version of the naturally occurring 43-amino-acid peptide Thymosin Beta-4, supplied strictly for laboratory and research use only.
Overview for Research Purposes
TB-500 is a synthetic peptide modeled after Thymosin Beta-4, a major actin-sequestering protein found in nearly all human and animal cells. In preclinical research models, it has been investigated for its potential roles in actin regulation, cell migration, tissue repair, and angiogenesis pathways.
Key Structural Features
• Sequence: Ac-LKKTETQ (active fragment commonly used in research; full Thymosin Beta-4 is 43 amino acids)
• Length: 7 amino acids (active core fragment); full native form is 43 amino acids
• Half-life: Relatively short in circulation (hours), often studied with repeated dosing or stabilized formulations in experimental settings
Primary Research Areas (Preclinical Models Only)
• Actin polymerization and cytoskeletal dynamics
• Cell migration and wound healing processes
• Angiogenesis and vascular growth factors
• Tissue regeneration and repair mechanisms
• Inflammation modulation and extracellular matrix remodeling
• Potential protective effects in models of injury or stress
Studies have explored TB-500's effects on tendon, ligament, muscle, and cardiac tissue repair, as well as corneal wound healing and hair follicle cycling. No large-scale human clinical trials have established safety or efficacy as of 2026.
