       Product Function


    Brief Introduction of TB500:

    TB500 (a synthetic molecule derived from the active domain of thymosin β4) is primarily used in anti-fibrosis and wound repair research. Specific applications include:


    1) Tissue Repair and Angiogenesis:

    TB500 accelerates wound healing and skin repair by inhibiting the Akt signaling pathway and promoting endothelial cell differentiation, dermal angiogenesis, keratinocyte migration, and collagen deposition.

    2) Anti-inflammatory Effects:

    Its active ingredients can reduce inflammatory responses, creating a favorable environment for tissue repair.

    3) Experimental Research:

    TB500 is commonly used in in vitro cell-based assays (such as T cell proliferation and cell survival promotion) and animal model studies. The solvent formulation should be adjusted according to experimental requirements.

    ※ Note: TB500 is for research use only. Specific applications must adhere to experimental protocols and literature guidance.



    Product Application


      • Research material for studies on immune regulation and cellular immune function.

      • Used in investigations of thymic peptides, bioactive peptides, and related biological mechanisms.

      • Applied in biotechnology, life science research, and functional ingredient development.

    FAQ

    1. How to make an order?
    Send me message and let me know what you need with quantity , then i will calculate to you

    2. What's the lead time and shipping ways?
    We will delivery to the package by UPS, FEDEX, DHL paket and YANWEN express to you after receive your payment, it would take around 5-15 days to your address.

    3. How do i keep the peptides when i receive it ?
    Peptides in the form of lyophilized powder can be transported at room temperature by vacuum packaging, while polypeptides in the dissolved state need to be refrigerated at 2°C - 8°C. For long-term storage, peptides should be stored in the form of lyophilized powder store at -20°C or -80°C in a sealed container with desiccant, which can avoid the degradation of peptides to the greatest extent.

    4. What's the payment methods?
    We could accept pay through Wise, Bank Transfer, Alipay USDT and BTC.

    ECHEMI Editorial Reference
    TB 500 is a synthetically made version of TB4 that facilitates healing and recovery by helping build new blood vessels, muscle tissue fibers, blood cells, and facilitating cell migration. It acts on the muscular system and has anabolic properties. TB 500 is used primarily for race animals (horses and dogs).

    Research
    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.
