      Product Detail 


    TB500 , officially known as Thymosin β4 Fragment 17-23, is an artificially synthesized short peptide consisting of 7 amino acids. It is also the core active fragment of thymosin β4. Its structure retains the actin-binding core domain of thymosin β4, thus possessing stable and specific biological activity. It mainly regulates the cytoskeleton by binding to actin, downregulates pro-inflammatory factors to achieve anti-inflammatory and anti-fibrotic effects, stimulates endothelial cell differentiation to promote angiogenesis, and activates stem cells such as muscle satellite cells to promote tissue structural reconstruction. It shows significant application potential in the repair of sports injuries, wound healing of skin and cornea, alleviation of chronic arthritis and soft tissue inflammation, as well as regenerative medicine research such as nerve, myocardial,  and liver fibrosis. TB500 is usually available in a freeze-dried powder form. When used, it needs to be diluted with sterile water and administered via subcutaneous or intramuscular. However, this substance is currently only used as a research reagent and has not been approved for human clinical treatment. Its long-term safety data is insufficient, and it has also been listed as a potential prohibited substance by some institutions. During use and research, strict adherence to relevant norms and regulations is required.

    Class:

    Actin-sequestering protein / 43-amino-acid peptide

    Status:

    Research compound — Not FDA approved (investigational: RGN-259 for dry eye / neurotrophic keratitis)

    Mechanism:

    A naturally occurring 43-amino-acid peptide (Ac-Ser-Asp-Lys-Pro-Asp-Met-Ala-Glu-Ile-Glu-Lys-Phe-Asp-Lys-Ser-Lys-Leu-Lys-Lys-Thr-Glu-Thr-Gln-Glu-Lys-Asn-Pro-Leu-Pro-Ser-Lys-Glu-Thr-Ile-Glu-Gln-Glu-Lys-Gln-Ala-Gly-Glu-Ser-OH) that binds G-actin (sequesters monomeric actin), preventing F-actin polymerization. Promotes cell migration, angiogenesis, wound healing, and anti-inflammatory responses via integrin-linked kinase (ILK) and HIF-1α/VEGF pathways. TB-500 is the synthetic fragment Ac-LKKTETQ (MW ~895) often sold under this CAS.

    Activity note:

    Thymosin Beta-4 is an actin-binding protein, not a receptor agonist. Functional activity is measured by actin sequestration (Kd ~0.7–1 μM) and cell migration assays, not EC₅₀.
