Overview
TB-500 is the synthetic, N-acetylated heptapeptide fragment Ac-LKKTETQ, corresponding to the actin-binding region (residues 17-23) of the naturally occurring protein Thymosin Beta-4. It is supplied as a lyophilised powder for laboratory research.
In research settings the fragment is studied in vitro and in animal models for actin regulation, cell migration, angiogenesis and inflammation-related signalling across multiple tissue types. It is supplied as a research reference material only and is not for human or animal consumption.
Research areas
- Actin-binding and actin-sequestering activity, studied in vitro
- Cell migration and angiogenesis, examined in preclinical models
- Pro-inflammatory cytokine signalling in tissue-research models
- Comparative studies alongside other tissue-research peptides

Storage and handling
Supplied as a lyophilised powder in a sealed vial and kept frozen until dispatch. Unopened vials are typically stored at -20°C for the long term and 2-8°C for short periods. After reconstitution with bacteriostatic water, vials are generally refrigerated at 2-8°C, protected from light, and not subjected to repeated freeze-thaw cycles.
