    High-purity lyophilized (freeze-dried) peptide powder. Each unit is individually vacuum-sealed in a glass vial to minimize air exposure, thereby significantly reducing the risk of moisture absorption and oxidation during storage and transport.
    We offer a range of specifications (5mg, 10mg, 15mg, 20mg, 30mg, and 40mg per vial) to flexibly meet the varying experimental protocols and dosage requirements of your research projects.
    Produced using an advanced, optimized lyophilization process, the resulting powder features a loose, uniform texture; it reconstitutes rapidly and completely upon the addition of solvent, leaving no insoluble residues, precipitates, or flocculent matter.
    We maintain ample, consistent inventory to support both sample orders and bulk wholesale. Cold-chain shipping is available upon request to ensure product stability during transit.

    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.
