    TB500, CAS No. 885340-08-9, is a synthetic peptide raw material widely used in peptide research, biochemical studies, laboratory development, and life science research applications. It is also commonly written as TB-500 in product catalogs and peptide supply channels. As a research-grade peptide compound, TB500 is commonly supplied in high-purity lyophilized form and is suitable for professional customers who require stable quality, reliable purity, and complete documentation support.

    TB500 is commonly described in research chemical catalogs as a synthetic version of an active region of thymosin beta-4. It is used in laboratory research related to peptide chemistry, peptide synthesis, analytical testing, biochemical assay development, and molecular research models. For B2B buyers, TB500 is mainly requested by biotechnology laboratories, research institutions, peptide distributors, pharmaceutical research companies, and chemical raw material suppliers.

    Our TB500 CAS 885340-08-9 is produced under strict quality control standards. The product can be supplied with professional testing documents according to customer requirements. Common quality documents may include COA, HPLC report, MS report, purity data, batch information, specification sheet, and other related technical documents. These documents help international buyers confirm product identity, appearance, purity level, molecular information, and batch quality before purchasing.

    As a peptide raw material, TB500 usually appears as a white to off-white lyophilized solid or fine solid material, depending on product specification and batch condition. It should be handled carefully in a clean and dry laboratory environment. Proper storage conditions are important for maintaining product stability and quality. The product is generally recommended to be stored in a sealed container, protected from moisture, heat, and direct sunlight. For long-term storage, low-temperature conditions are usually preferred. After opening, users should reseal the package properly and avoid repeated exposure to air and humidity.

    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.
