TB-500 (Thymosin β4) for Research
Technical Overview
TB-500 is a synthetic version of a peptide fragment derived from thymosin beta-4, a protein with a key role in tissue repair and cellular regeneration. It is used in research on tissue repair, wound healing and muscle recovery, and is a central focus of studies on injury recovery and cellular repair processes.
Research applications
- Tissue regeneration: how the peptide promotes production of actin, a protein essential to cell structure and movement, to support cellular repair.
- Wound healing: its role in tissue recovery and in angiogenesis, the formation of new blood vessels that carry oxygen and nutrients to damaged tissue.
- Inflammation modulation: how TB-500 influences inflammatory cytokines and supports tissue under stress or injury.
- Muscle and tendon repair: its potential in muscle regeneration and tendon recovery after injury.
Mechanisms under study
Researchers analyze how TB-500 drives actin production and accelerates angiogenesis, and how these effects combine to aid recovery and cellular repair. Work also covers its role in tissue flexibility and in models of muscle regeneration, tendon recovery and injury prevention, making it a common subject in studies related to physical rehabilitation and tissue resilience.

Storage & Intended Use
Storage Instructions
Handling and Storage Tips:
- On arrival, store the sealed vial at −20 °C, protected from light and moisture.
- For short-term storage (days to weeks), refrigeration at 2–8 °C is acceptable.
- Lyophilized peptides tolerate room temperature for short periods, such as during shipping.
- Let the vial reach room temperature before opening, to avoid condensation.
- Once reconstituted, keep refrigerated at 2–8 °C and avoid repeated freeze–thaw cycles.

Answers
Frequently Asked Questions
Is TB-500 third-party tested?
Yes. Each lot is tested by Bioviridian, an independent HPLC-MS laboratory, for identity (mass spectrometry), purity (RP-HPLC), content and endotoxin, and the Certificate of Analysis is published for that lot.
Can I see the Certificate of Analysis before buying?
Yes. Download it from the Documents section above, or search the lot number in our COA library.
What does 'Research Use Only' mean?
Products are supplied only for laboratory research. They are not drugs, foods, supplements or cosmetics and are not for human or veterinary use.
How is it shipped and stored?
Cold-packed with tracking, same day on orders by 2 PM ET. Store lyophilized vials at −20 °C on arrival.
