Product OverviewTB-500 has attracted research interest for its potential role in tissue repair, cellular migration, and recovery-related biological processes. Research associated with this peptide focuses on supporting cellular movement, regulating inflammatory responses, promoting angiogenesis, and maintaining normal cellular function. It is also studied in relation to muscle tissue recovery, wound healing mechanisms, and the body's natural repair processes. These properties make it an interesting subject in regenerative biology and cellular research. Its potential effects and applications remain under investigation and have not been established as approved therapeutic benefits in humans.![Shop 5mg TB500/BB10/BB20, 99% purity, CAS 885340-08-9, good price, raw powder.-Detailed Image 2]()

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.
