DOWNLOAD FULL REPORT (PDF)TB-500 (Thymosin Beta-4) is a synthetic research peptide that mirrors a 43-amino-acid sequence of the naturally occurring actin-sequestering protein found in many tissues. It plays a significant role in cellular motility, tissue repair, and regeneration by modulating the polymerization and organization of actin filaments.
In preclinical models, TB-500 has been studied for its ability to influence cell migration, angiogenesis, and inflammatory responses. By regulating the G-actin/F-actin balance and promoting the expression of critical growth factors, TB-500 is a key tool in regenerative peptide research.
- Alias: Thymosin Beta-4 (Tβ4)
- Sequence: SDKP… (43 amino acids)
- Molecular Formula: C212H350N56O78S
- Molecular Weight: ~4963.5 Da
- Purity: ≥98% (HPLC verified)
- Form: Lyophilized peptide
- For Research Use Only: Not for human or veterinary use
All peptides are supplied as sterile, lyophilized powder and are stable when handled correctly.
- On arrival: Store vials in a cool, dry place away from heat and direct sunlight.
- Long-term (powder): For optimal longevity, keep lyophilized peptides refrigerated to help maintain integrity.
- After reconstitution: Use an appropriate research diluent (for example, BAC water). Store the reconstituted solution in the refrigerator and use within 20–30 days for best stability.
Note: Minimize exposure to moisture and repeated freeze–thaw cycles. Follow your institution's safety procedures when handling research materials.
Q: What is TB-500 derived from?
A: TB-500 is a synthetic peptide modeled after the natural protein Thymosin Beta-4, found in various mammalian tissues.
Q: What is the primary function of TB-500 in research?
A: It is used to study cellular migration, angiogenesis, and wound healing through actin cytoskeleton regulation.
Q: Is TB-500 injectable?
A: While some experimental studies use injection as a delivery method in animal models, TB-500 is strictly for research purposes and not for human administration.
Q: Can TB-500 promote muscle or tendon repair?
A: In preclinical studies, TB-500 has shown potential for improving soft tissue recovery in musculoskeletal models.
Q: Does TB-500 affect inflammation?
A: Yes. It has been studied for its anti-inflammatory and oxidative stress modulating properties, making it useful in systemic recovery models.
