      Product Detail  


        TB500, also named Thymosin Beta 4 Acetate, is a premium synthetic peptide derived from the active fragment of natural Thymosin β4. Supported by strict HPLC testing, the peptide purity reaches ≥98.0%, guaranteeing stable and reliable experimental outcomes for global researchers. The raw material is presented as white lyophilized crystalline powder. We offer flexible specifications of 5mg/vial and 10mg/vial, packed 10 vials in a sealed plastic storage box to avoid contamination and facilitate convenient storage and transportation.

        Widely applied in academic research focusing on tissue repair, angiogenesis and anti-inflammation, TB500 functions by regulating intracellular actin. It promotes endothelial cell differentiation, dermal angiogenesis, keratinocyte migration and collagen deposition to support wound regeneration in lab models. Moreover, it alleviates inflammatory responses after tissue injury and builds a favorable microenvironment for damaged tissue recovery. It fits well with in vitro cell tests including T cell proliferation and cell survival assays, as well as animal studies targeting muscle, tendon and joint injury recovery.
    Different from other thymosin peptides mainly for immune modulation, TB500 features prominent tissue regeneration properties. We maintain sufficient in-stock supply, support customized packaging and provide complete product specifications for your laboratory projects.

        Important Notice: This product is exclusively for laboratory research use only. It cannot be used for human administration, clinical therapy or animal treatment. Researchers should prepare solvent strictly following experimental protocols and published academic literature.

    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.
