Chemical and structural properties
What it is
TB-500 is a synthetic seven-amino-acid peptide (Ac-LKKTETQ) copied from the actin-binding region of thymosin beta-4, studied in tissue-repair research.
Molecular profile
Storage
The actin-binding core of thymosin beta-4, made as a short synthetic peptide for tissue-repair research.
TB-500 is the seven-amino-acid sequence Leu-Lys-Lys-Thr-Glu-Thr-Gln, acetylated at its N-terminus, copied from positions 17 to 23 of thymosin beta-4. That stretch holds LKKTET, the motif thymosin beta-4 uses to bind G-actin, the building block of the cell's actin skeleton.
Research uses TB-500 to study cell migration, wound closure, blood-vessel growth, and repair of muscle, tendon and skin in animal and cell models, and to separate what the actin-binding region does from the rest of thymosin beta-4.
TB-500 is a synthetic seven-amino-acid peptide, Ac-Leu-Lys-Lys-Thr-Glu-Thr-Gln, copied from the actin-binding region of thymosin beta-4, a protein found in nearly every human cell.
No. Thymosin beta-4 is the full 43-amino-acid protein. TB-500 is a synthetic copy of positions 17 to 23, the part that binds actin, which is why the two are studied and discussed together.
TB-500 is studied in tissue-repair research, including cell migration, wound closure, blood-vessel growth and muscle and tendon repair in animal and cell models.
Yes. The Wolverine peptide combines 10mg of BPC-157 and 10mg of TB-500 in one vial.
Keep the sealed vial in the refrigerator at 36–46°F (2–8°C), dry and away from light. As a freeze-dried powder it tolerates room temperature for weeks, which is why it ships without ice. Once reconstituted, keep it refrigerated between uses. More in our guide, Do peptides need to be refrigerated?
TB-500 comes as a white lyophilized powder in a 10mg vial.
No. TB-500 is sold for laboratory research use only.
