       Product Detail  


    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).

    Mechanism of action

    Blood vessels are an essential precondition for any biochemical activity, including cell proliferation, tissue repair and remodeling, and other activities. In animal and in vitro models,, which line blood vessels. Through its potential to stimulate migration, TB-500 may have the prospect of stimulating the formation of blood vessels in animal models, even in tissues such as cartilage. Findings imply that by promoting cell development, TB-500 may assist in tissue repair and help guarantee that the repair is more comprehensive. It was speculated via research conducted on mice models of heart attack that TB-500 might stimulate the creation of capillary tubes, promoting heart muscle regeneration and preventing heart cell death after damage. In a nutshell, TB-500 may both discourage cell harm and promote cell healing once it has already occurred.

    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.
